Section 1: General Information
1.0 Introduction
This section provides the general information for the Teledyne Paradise Datacom LLC line of
Compact Outdoor Solid State Power Amplifiers. The Compact Outdoor SSPA has been
designed and manufactured to be an extremely robust and reliable amplifier. It is well suited
for harsh outdoor environments.
1.1 Description
The Compact Outdoor SSPA is a one-piece integrated Satcom amplifier system. It includes
the AC/DC power supply, microwave amplifier module, microprocessor based monitor and
control circuitry, and an efficient thermal management system.
The Compact Outdoor SSPA is very well suited for environmentally demanding conditions
where reliability is paramount. At the heart of the amplifier system is a multifunction solid state
power amplifier (SSPA) module. It has a full compliment of parallel I/O monitor and control
signals as well as serial I/O capability using a PC and host communication software from
Teledyne Paradise Datacom LLC.
Proprietary thermal management techniques allow even the highest output power level amplifiers to operate reliably in environments up to 60°C ambient temperature and 100% relative
humidity.
The reduced size and weight of this amplifier system allow it to be used in a wide variety of
installations; many of which historically precluded the use of Solid State power amplifiers.
This amplifier is ideal for mounting on the boom of small antennas or anywhere that size and
weight are a major concern.
Features include:
• Compact Size: 10.0 in x 19.5 in x 6.50 in. (254 mm x 495 mm x 165 mm)
• Very light weight: Base units weigh as little as 36 lb. (16.4 kg)
• Auto-Sensing Power Factor Corrected Power Supply
• RF Gain Adjustment: 55 dB to 75 dB minimum with 0.1 dB resolution
• Output Power Detection
• Output Power Sample Port
• Internal 1:1 Redundant Capability
• Optional L-Band Input Capability

1.4 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working with this
unit. To ensure safe operation, the user must follow the information, cautions, and warnings
provided in this manual as well as the warning labels placed on the unit itself.
1.4.1 High Voltage Hazards
Only qualified service personnel should service the internal electronic
circuitry of the Compact Outdoor Amplifier. High DC voltages (300 VDC) are
present in the power supply section of the amplifier. Care must be taken
when working with devices that operate at this high voltage levels. It is
recommended to never work on the unit or supply prime AC power to the unit while the cover
is removed.
1.4.2 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin
burns. Prolonged exposure to high levels of RF energy has been linked to a
variety of health issues. Please use the following precautions with high levels
of RF power.
• Always terminate the RF input and output connector prior to applying prime AC
input power.
• Never look directly into the RF output waveguide
• Maintain a suitable distance from the source of the transmission such that the power
density is below recommended guidelines in ANSI/IEEE C95.1. The power density
specified in ANSI/IEEE C95.1-1992 is 10 mW/cm
OSHA Standard 1910.97.
• When a safe distance is not practical, RF shielding should be used to achieve the
recommended power density levels.

1.5 Comparisons Between Standard and Mini Compact Outdoor SSPAs
In 2010, Teledyne Paradise Datacom introduced a smaller outdoor SSPA package based on
the standard Compact Outdoor SSPA described in this manual.
While similar in function, there are some differences that prevent immediate substitution of a
Standard Compact Outdoor unit type with a Mini Compact Outdoor unit in a system. Some of
the differences between the Standard and Mini Compact Outdoor amplifiers are outlined
below:
• AC Mains connector
• Slight variation in protocol
• No analog gain control on J4 in Mini Compact Outdoor SSPA
• No RF Power Detector analog output on J4 in Mini Compact Outdoor SSPA
• No Low RF Fault output on J4 in Mini Compact Outdoor SSPA
• No BUC Alarm output on J4 in Mini Compact Outdoor SSPA
• No Spare Input on J4 in Mini Compact Outdoor SSPA
Due to the size differences between the standard Compact Outdoor SSPA and the Mini
Compact Outdoor SSPA, the following form factors also differ:
• Mounting kit configuration
• Waveguide center line measurements
• Location of connectors

2.2.1 RF Input (J1) [N-type (F)]
The RF Input connector is a type N female connector. The Compact Outdoor SSPA has a
default maximum nominal gain of 75 dB minimum. Therefore the maximum input signal
required to saturate the amplifier can be calculated as:
Input Power = P
- 75 dB
sat
For example, if a 50 W Ku-Band Compact Outdoor amplifier is used in a system it has a P
sat
=
47.0 dBm. Therefore the maximum input power should be limited to -28 dBm. Slightly higher
input power levels will not damage the amplifier but will result in higher levels of distortion in
the output signal.
WARNING! The maximum input level should be limited to +15 dBm to
avoid damaging the amplifier.
Figure 2-2 shows the input side of the Compact Outdoor Amplifier. This side contains the RF
input (J1), M&C input (J4), and the Interface connections (J5, J6).

18 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
The power supplies provide universal AC input by using auto-sensing power supplies. The
AC input can operate over a range of 90-265 VAC, at 47 to 63 Hz. The power supply is also
power factor corrected, enabling the unit to achieve a power factor greater than 0.93.
The prime power vs. RF output power is summarized in Table 2-6 on the following page. An
option for 110 VAC prime power is available for the higher-powered units.
The highest output power levels, >70 W @ Ku-Band and >100 W @ C-Band should be
powered only from a 180–265 VAC source. This will keep AC line currents to safe operating
levels for the internal EMI filter and associated circuitry.
2.2.7.1 DC Input Option [MS3102E-20-29P]

2.3 Physical Features
In addition to the I/O connectors, the Compact Outdoor user-friendly features include a summary alarm indicator and removable fan tray.
2.3.1 Summary Alarm Indicator
A summary alarm indicator LED is located on the input side of the amplifier. When the SSPA
is online, this indicator illuminates GREEN. When in a fault condition, it illuminates RED.
2.3.2 Airflow and Removable Fan Tray
The Compact Outdoor Amplifier’s cooling system represents a landmark in microwave telecommunication amplifiers. It features a unique system of heatsinks that have been computer
optimized to provide extremely efficient cooling of all of the system’s functional blocks. This
high efficiency cooling system is primarily responsible for the small overall package size and
reduced weight of the unit (approximately 36 lbs or 16.4 kg).
The cooling system is based on a forced convection technique in which the system fans provide the air intake while the exhaust is brought out around the outer perimeter of the fans.
The air intake and exhaust are both located on the bottom side of the amplifier. The intake is
brought through three fans while the exhaust is along the two rows of heatsink fins as seen in
Figure 2-3.
A minimum clearance of 6 inches (152 mm) should be maintained between the bottom of the
amplifier and any mounting surface. This will ensure that there is no forced re-circulation of
airflow from exhaust to intake.
The Compact Outdoor SSPA should NEVER be mounted with the fans facing up.
The fans should be examined periodically and any obstruction or debris should be cleared.
Inadequate air flow can cause the amplifier to overheat and cause a temperature fault. See
Section 6: Troubleshooting and Maintenance for instructions on how to clean the fan
assembly and heatsink.
In system configurations, ensure that each unit in the system
has sufficient ambient airflow, and adequate space to maintain
the fans for each unit. Figure 2-5 shows an improper method
for mounting a Compact Outdoor SSPA system. Not only do
the fans oppose each other, thereby potentially causing thermal
issues, but the configuration leaves insufficient space to re-
move the fans to periodically clean the heatsink.
The fans provide a maximum air flow of 103 CFM each
(maximum air pressure of 0.691 inches H2O at zero air flow)
and produce 54.0 dB-A measured at a distance of 1 meter from
the fan intake.

3.1.1 Amplifier Enable (Mute/Unmute) (J4)
The Compact Outdoor Amplifier has no on/off switch or circuit breaker in the AC Input path.
As soon as AC power is applied to J7, the unit’s power supplies and microcontroller are
enabled. The operator will be able to observe the forced convection cooling fans running.
However, the internal amplifier module is disabled until the Mute Line Input (J4 – Pin B) is
pulled to Ground (J4 – Pin V).
If it is desired to have the RF enabled every time the AC input is applied, a permanent
connection can be made from J4-Pin B and Pin V.
3.1.2 Gain Adjust Input (J4)
The Gain Adjust Input allows an analog voltage that is applied between (J4 – Pin A) and
Ground (J4 – Pin V) to control the gain of the amplifier. The gain is adjustable over a 20 dB
range with 0.1 dB resolution. The applied voltage is directly proportional to amplifier gain.
2.5 VDC = Maximum Gain: 75 dB
0.5 VDC = Minimum Gain: 55 dB
The Compact Outdoor SSPA is factory default to have maximum gain with no analog gain
adjust. The gain adjustment must be enabled by running the setup program from a host PC.
This prohibits any accidental gain adjustments that may occur from unintentional analog
voltages that may be present on the Gain Adjust Control J4-Pin A.
The gain is also adjustable using a host PC and the supplied Teledyne Paradise Datacom
Universal Monitor and Control program. See the Serial I/O Section for details on Serial
Control.
3.1.3 Alarms (J4)
A variety of alarm signals are present at the M&C connector, J4. Both Form-C relays and
open collector outputs are available. An amplifier summary alarm is available in both Form C
relay and open collector output. Detailed internal faults are available in open collector form
and include: voltage, current, and over-temperature.
3.1.3.1 Summary Alarm (J4) Form C Contacts
The Summary Alarm is accessible in both Form C relay and open collector format. The form
C relay is “energized” under normal operating conditions and “deenergized” when a fault
condition exists.
3.1.3.2 Auxiliary Alarm (J4) Form C Contacts
The Auxiliary Alarm relay is an end user alarm that can be used to signal an alarm condition
that is dependent on the state of the Auxiliary Input (J4-Pin P).
32 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
The Auxiliary Input is a contact closure to ground. When this input is pulled to ground the
Auxiliary Alarm relay is energized (Normal State). When the Auxiliary Input is open circuited
the Auxiliary Alarm relay is de-energized (Alarm State).
One example usage of the Auxiliary Alarm is that it could be used to signal one of the detail
alarms (voltage, current, or temperature) by connecting the appropriate open collector alarm
output to the Auxiliary Input. This programs the Auxiliary Alarm relay to be either a voltage,
current, or temperatue Form C relay alarm.
3.1.3.3 Open Collector Alarm Outputs (J4)
The open collector alarm outputs will require external pull-up resistors (unless connected to
the Auxiliary Input). They are capable of sinking up to 20 mA current at 30 VDC. The open
collector outputs are pulled to ground under normal operating conditions and switch to high
impedance state during an alarm condition.
Low RF Alarm: follows state of Auxiliary Input as described above
BUC Alarm: high when amplifier’s internal regulator voltage falls below its acceptable
level
3.1.4 RF Power Detector (J4)
The RF Power Detector is an analog output voltage that is proportional to the RF output
power. The maximum output voltage is 4.0 VDC which corresponds to the maximum
(saturated) output power from the amplifier. This detected voltage is useful over a 20 dB
range of output power.
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 33
3.2 Quick Start Cables

3.4.1.1 Signal Indicators
Three rows of indicators show the connection status of the connected
amplifier. Top-most is an indicator that displays a green square when
Connected, or a red square when Disconnected. Immediately below are two
indicators for the TX and RX paths. The third row displays the mute state
(Carrier Enable). This is actually a toggle which allows the user to Enable or
Mute the amplifier.
38 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
Figure 3-12: Fault Indicators
3.4.1.2 Fault Status Indicators
The Fault Status frame in the lower left side of the Status Window contains a 3x4 grid of
SSPA fault lights. See Figure 3-12.
Summary Alarm: The Summary Alarm is simply a logical ‘OR’ of any of the alarm indicators.
Low DC Current Alarm: The Current Fault is factory preset to alarm if the SSPA module
current falls below 60% of its nominal value.
BUC Alarm: The BUC fault is only active in units that are supplied with an optional L-Band
Block Up Converter module. If the Up Converter’s phase locked local oscillator loses lock, a
BUC alarm is set and the amplifier is muted so that spurious RF cannot be transmitted.
Auxiliary & Spare Alarms: The Auxiliary and Spare Alarms are configurable from the
Settings Window. See Section 3.4.2.
High Temperature Alarm: The Temperature Fault indicator is factory preset to alarm at
80°C. The amplifier will continue to operate up to 90°C. Beyond 90°C the DC power will be
interrupted to the SSPA module. This measure will protect the sensitive microwave transistors
from catastrophic failure. The fans and monitor and control circuitry will continue to operate
normally. This function has approximately a 5°C hysteresis window which will allow the
amplifier to re-enable itself when the ambient temperature is reduced by 5°C. The
Temperature Alarm is intended to warn the operator of possible fan problems and eventual
amplifier shutdown.
Low DC Voltage Alarm: The Voltage Alarm is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value.
RX Checksum Alarm: The RX Checksum Alarm indicates when an invalid checksum byte is
communicated to the unit.
External Mute Alarm: The External (Ext) Mute line gives an indication via the M&C screen
that the SSPA has been externally muted by J4-Pin B. This external mute alarm can be configured to trigger a summary alarm if desired. The factory default is to signal a External Mute
fault but no Summary Alarm.
RF Switch Alarms: The RF Switch 1 Alarm is only active if a 1:1 Redundant System has
been configured in the M&C program. The RF Switch 2 Alarm is only active is a 1:2
Redundant System has been configured. These configurations are covered in Section 7.
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 39
3.4.1.3 Voltage, Current and Temperature Display
On the right side of the Status window there is a thermometer
display that reports the present baseplate temperature of the
amplifier. The baseplate temperature typically experiences a
20-30 degree rise above ambient on the highest power Compact
Outdoor amplifiers and 15-20 degree rise on lower power units.
To the left of the thermometer display are several indicators that
show various operating conditions of the Compact Outdoor Amplifier
in real time. These indicators are helpful for any diagnostic
procedures and consist of:
• Power Supply Voltage monitor
• SSPA DC Current monitor
• Regulator Voltage monitor
• Gate Voltage monitor
The Power Supply voltage indicator displays the primary 12 volt power supply output. SSPA
DC Current is the total current drawn by the microwave transistors. Regulator Voltage is the
DC voltage of the drain circuitry that feeds the GaAs transistors. The Gate Voltage indicator
monitors the DC voltage of the gate circuitry of the microwave GaAs transistors. These
indicators provide direct access to the active device operating characteristics.
3.4.1.4 Gain Adjustment
The Gain Attenuation Control is located above the Fault Condition Indicators and to the right
of the Carrier Enable status. The gain can be adjusted by setting the Attenuation Control. An
Attenuation Control of 0 dB is the maximum gain (75 dB) setting on the amplifier. By setting
the Attenuation Control to 20 dB; the gain is set to (55 dB). The Attenuation Control can be
varied using the control knob or the forward/reverse buttons.
Note the illuminated PC Control button inside the Attenuation Control frame. This control
allows the gain adjustment function to be assigned to the analog input voltage (J4-Pin A). The
gain adjustment control must be either under PC control or analog voltage control; it cannot
be both.
3.4.1.5 RF Power Indicator
The RF Power indicator is the vertical meter in the central part of the Operation window. This
indicator reports the approximate output power of the amplifier. It uses the voltage from the
RF Power Detector to determine a corresponding power level in dBm. The accuracy of the
power indicator is ±1 dB at the mid-point of the specified band, with a single CW or QPSK
carrier.

3.4.3 IP Setup Window
If the user wishes to set up the networked Compact Outdoor SSPA with custom IP settings,
the internal IP settings need to be modified. Click on the IP Setup Tab. See Figure 3-15.
• The SSPA will use the default settings until the unit is reset by removing its AC
power. Unplug the Quick Start cable from the M&C connector. (If the unit is
restarted with the Quick Start cable connected, it will always come up with
default IP settings). Apply power to the SSPA. Re-plug the Quick Start cable
into J4, and check connectivity with the custom IP settings.
• Make sure that the Protocol setting in the Settings tab of the Universal M&C is
set to IPNet, as shown in Figure 3-13.
• If custom IP settings will be used in normal operation, the user will need to con-
struct an IP cable or modify the Quick Start Cable by disconnecting the interface
control pins (pins j and e, Baud Select 0 and Baud Select 1) from ground. In this
configuration, the SSPA will always use the saved communication control settings rather than the default configuration.

Section 4: L Band Operation
4.0 Block Up Converter Overview
The Compact Outdoor SSPA is available with various L-Band up converter options. The
primary up converter option is the Zero dBm Block Up Converter, ZBUC
converter is offered in four C-Band configurations, two Ku-Band options, and one X-Band
model. See Table 5-1 for specifications for the respective models. The ZBUC converter offers
ultra low phase noise for applications where phase noise is an overriding factor.
The type of BUC housed within your Compact Outdoor SSPA is indicated by its model
number, as shown in Figure 4-1. The example in Figure 5-1 shows a 140W C-Band
Compact Outdoor SSPA with Internal Reference ZBUC. For a full description of this
configuration matrix, refer to the Compact Outdoor SSPA specification sheet (205485).

The block up converters are high performance frequency translation devices which
provide excellent phase noise and spurious performance. The ZBUC converter also supports
FSK communications for remote M&C capability. The FSK is a 650 KHz signal that is multiplexed onto the L-Band input of the unit.
The ZBUC converter utilizes Teledyne Paradise Datacom’s proprietary “Smart Reference
Technology”. Smart Reference Technology allows the system user to change reference
frequency and power level or choose internal or external reference without requiring any
system configuration. An internal BUC adds about 1.7 pounds to the overall weight of the
Compact Outdoor unit.
The schematic of Figure 4-2 shows the electrical position of the block up converter. It is
powered from a +15 VDC supply available on the Fan Boost Converter board assembly. The
Block Up Converter is simply cascaded with the SSPA at the input of the amplifier.

It is important to remember the requirement of a 10 MHz reference oscillator when operating
an SSPA with BUC (SSPB). If the 10 MHz reference is not present, the M&C will report a
BUC alarm and the SSPA module will mute. This ensures that no spurious or ‘off frequency’
transmission could originate from the amplifier.
Note: Unless the BUC has the built-in internal reference option, if there is an absence
of a 10 MHz reference signal on the IFL input there will be no output signal from the
SSPA.
4.1 ZBUC Features
This section describes the features available in the Teledyne Paradise Datacom ZBUC converter. The ZBUC converter is available as an option for the Compact Outdoor SSPA, and is
available in four C-Band models, two Ku-Band models, one X-Band model, and one Ka-Band
model. Table 4-1 shows the specifications for the respective models.

4.2 ZBUC Converter Theory of Operation
The ZBUC converter is a low gain block up converter with a P
allows the system to be integrated with little impact on the general electrical specifications of
the SSPA module.
The ZBUC converter utilizes single up conversion from L-Band to the desired RF band. The
local oscillator circuits are designed to maintain the lowest possible output phase noise. The
frequency synthesizer utilizes industry leading technology which allows for phase noise
performance previously unattainable in PLL design. Typical phase noise specifications are
outlined in Table 4-2.

Band selectivity is accomplished using the most aggressive filtering possible while maintaining specified power and spurious performance.
4.3 Smart Reference Technology
Teledyne Paradise Datacom’s new ZBUC converter comes standard with smart reference
technology. Smart reference technology allows the system operator to change external
system reference frequency without any system configuration required. The ZBUC converter
will automatically sense and lock to any one of the following system reference frequencies: 5,
10, 20, 25, and 50 MHz. With the internal reference option installed the ZBUC converter will
operate with no external reference applied. In the event the system operator wishes to
operate on external reference, the ZBUC converter will automatically sense the presence of
an external reference and switch to external reference mode. With the internal reference
option installed, the internal reference also becomes a backup reference which will become
active in the event that external system reference is lost.
External reference is applied to the ZBUC converter via the L-Band input IFL and is routed to
the frequency synthesizer using the built-in demux circuitry.
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 53
Notes:
1) The external reference option requires the system operator to provide system
reference to the ZBUC/SSPB. The system will not lock and will have no output
without external reference applied.
2) Internal reference option allows for either internal or external reference operation.
The 10 MHz crystal reference used in the internal reference of the ZBUC converter has the
following specifications:
Frequency Stability: ≤±1 • 10-8 over the temperature range -40 to +90 °C
≤±1 • 10-9 aging per day

4.4 ZBUC FSK Monitor and Control
FSK Monitor and control comes standard with the ZBUC converter. This allows the Compact
Outdoor SSPB to be fully and remotely monitored and controlled through the system’s IFL. An
embedded controller enables remote communication and fault detection via the IF input
between the SSPA and a Teledyne Paradise Datacom Evolution Series L-Band modem. This
signal consists of a 650 KHz Frequency Shift Keyed carrier that is multiplexed onto the
L-Band input IFL along with the 10 MHz reference signal. The M&C functionality is explained
in detail in Section 10.
The FSK input has a center frequency of 650 KHz with a ±5% tolerance. The FSK deviation is
±60 KHz, with +60 KHz being a “mark” and -60 KHz being a “space”. The FSK input will work
over an input power range of -5 to -15 dBm. The FSK characteristics are summarized below:
Frequency 650 kHz ± 5%
FSK Deviation ± 60 kHz nominal (+60 kHz mark)
Deviation Tolerance ± 50 kHz minimum, ± 70 kHz maximum
Locking Range ± 32.5 kHz
Input Level Range -5 to -15 dBm
Start Tone Time 10 ms minimum
See Teledyne Paradise Datacom document number 201410 for a full description of the VSAT
BUC Protocol.

4.6 IFL Cable Considerations
Consideration should be given to using a high quality IFL between the indoor equipment and
Compact Outdoor SSPB. The system designer must always consider the total cable loss for a
given length and also the implications of the slope of attenuation across the 950 to 1450 MHz
bandwidth. Table 4-3 gives the approximate attenuation vs. frequency for a variety of cable
types.

the particular installation including the cable’s temperature range. Also make sure the coaxial
connector from the IFL cable to the Compact Outdoor input is wrapped with a weather sealing
tape to prevent water intrusion into the coaxial cable.

Section 6: Performance Tests
6.0 Introduction
This section describes some of the tests performed on production amplifiers before shipment.
Where possible, Teledyne Paradise Datacom LLC maintains computer automated RF test
stations to ensure a high level of accuracy and consistency to production amplifier testing.
6.1 Standard tests
All Teledyne Paradise Datacom Compact Outdoor amplifiers must meet rigid specifications
and undergo the following tests. Copies of the final test data are shipped along with the unit
and/or system. Figures 6-1 through 6-3 show examples of the final test data for a 140W
C-Band Compact Outdoor amplifier with an integrated block up converter.
6.1.1 Swept Gain
The amplifier gain is swept over the operating frequency range under small signal conditions
to confirm the minimum gain and gain flatness specifications. The entire Compact Outdoor
amplifier is tested in a temperature chamber from -40 °C to +55 °C and the gain is recorded.
See Figure 6-1, item [1].

Figure 6-1: Spurious and Gain Data
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 61
6.1.2 Spurious
Spurious signals are undesirable byproducts of amplifiers caused by nonlinearities within the
amplifier and other system level components such as switch mode power supplies. These
unwanted signals cause signal management problems in system applications. Out of band
spurious signals cause interference to other pieces of equipment. See Figure 6-1, item [2].
6.1.3 Input Return Loss
The input return loss is measured in all production amplifiers. This is a measure of how
closely the amplifier is matched to its characteristic impedance. The input impedance of the
amplifier is a nominal 50Ω. See Figure 6-2, item [1].
6.1.4 Output Return Loss
The output return loss is measured in all production amplifiers. This is a measure of how
closely the amplifier is matched to its characteristic impedance. The output impedance of the
amplifier is matched to the waveguide complex impedance. See Figure 6-2, item [2].

62 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
6.1.5 Intermodulation Distortion
Intermodulation distortion is one of the most important characteristics of a Solid State power
amplifier system. Satellite communication systems must comply to certain distortion levels
depending on the service involved. All production amplifiers are subjected to automated
intermod testing. This is based on a standard two-tone intermod test in which the intermod
level (IMD) is measured in dBc with respect the main tones and the highest third order
intermod products.
Satcom amplifiers are typically used in some ‘back-off’ condition. This is the operating point at
which the composite output power is ‘backed-off’ from the amplifier’s P
, compression point.
1dB
A curve of back-off vs. IMD level is especially useful in the selection of a power
amplifier or determining the proper output power setting in a Satcom system.
Teledyne Paradise Datacom recognizes the importance of this back-off characteristic and
provides a plot of back-off vs. IMD from 1 dB to 10 dB back from the amplifier’s compression
point. Figure 6-2, item [3], shows a typical back-off curve from a production test set.
6.1.6 Power Requirements
This test measures the power requirements of the unit over the various voltages appropriate
for the unit under test. See Figure 6-3, item [1].

6.1.7 Earth Ground
This test measures the leakage current and verifies that each pin on J8 is connected
correctly. If the ISO/GND compatibility jumper is equipped, it verifies the jumper position. See
Figure 6-3, item [1].
6.1.8 Sample Port
The RF Sample Port is measured at discrete frequencies across the band and a calibration
label is placed near the Type N connector on the bottom of the unit. The sample port is
approximately -40 dB from the RF output level. A label with the exact coupling ratio is
attached to the amplifier chassis. See Figure 6-3, item [2].
6.1.9 P
1dB
and P
sat
The 1dB Gain Compression Point is measured at discrete frequencies across the band to
characterize the output power over the operating frequency range. The P
measurement is
1dB
a guaranteed minimum specification.
As the input power increases, the output power limits to some maximum level. This is defined
as the saturated output power or P
. The P
sat
specification is a typical value and is not
sat
guaranteed. This is due to the variation that exists among microwave power semiconductors.
The saturated output power is typically 0.5 dB to 1.0 dB above the P
value. See Figure
1dB
6-3, item [3].
6.1.10 I/O Test
This test verifies that the unit has the correct wiring on the MS connectors by testing faults,
communications, and redundancy. See Figure 6-3, item [4].
6.1.11 Ethernet (if equipped)
Tests Ethernet communication, web monitor and control, and assigns a MAC address to the
unit.

Section 7: Maintenance
& Troubleshooting
7.0 Introduction
This section describes some of the standard maintenance practices that can be performed on
the Compact Outdoor Amplifier and tips to troubleshoot common customer issues.
7.1 Cooling System Maintenance
It is recommended that the cooling system be checked at least once per month. This involves
visually inspecting the fan intakes to make sure that there is no obstructions over the intake.
The Windows-based M&C program can be used to check the amplifier base plate
temperature. The base plate temperature should normally not exceed a 30°C to 35°C rise
above the current outside ambient temperature. If the base plate temperature exceeds this
temperature rise, it is one indicator that the system’s airflow requires maintenance.
The heatsink fins in the exhaust path can be visually inspected for excessive dirt and debris
buildup. If it appears there is excessive debris in the heatsink; the fan tray can be removed
for easy cleaning. Failure to keep the fans and heatsink clear of debris will void your
warranty.
7.2 Fan Removal and Heatsink Cleaning
It is recommended to remove prime AC power from the amplifier when the fan tray is being
removed. However, if necessary, the fan tray can be removed while the amplifier is operating.
Caution should be used to make sure that no clothing or fingers are caught in the fan blades.
Simply remove the four screws from the fan tray and the fan assembly can be removed from
the bottom of the amplifier assembly.
The fans are connected to their power source by weatherized in-line circular connectors. A
replacement fan with connector can be provided for replacement. While the fan tray is
removed, the heatsink fins can be cleaned by spraying compressed air throughout the finned
area. A can of dust remover spray such as that which is found at a computer or electronics
shop will work fine. All debris should be removed before installing the fan tray.
Figure 7-1: Fan Removal from Amplifier Assembly
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 67
7.2.1 Fan Replacement
Older models of the Compact Outdoor SSPA were fitted with a two fan cooling fan assembly.
The newer models utilize a three fan cooling fan assembly.
While the fan interface connectors for the two fan and three fan tray assemblies are identical,
they should not be used interchangeably.
If your Compact Outdoor SSPA was shipped from the factory with the three fan air intake tray,
any maintenance requiring replacement of the fans should only use the three fan kit (L205192
-1). The three fan kit requires 12 VDC directly from the buss bar and draws 5.9 A (70 W).
If your Compact Outdoor SSPA was shipped from the factory with the two-fan air intake tray,
any maintenance requiring replacement of the fans should only use fan kit (L201814-1). This
kit replaces one fan on the fan tray assembly. The two fan kit requires 28 VDC from the
booster circuit card assembly and draws 0.7 A (19 W).
Note: Failure to use the proper fan tray will damage your amplifier!
It is possible to modify an older Compact Outdoor SSPA to be fitted with a three fan cooling
fan assembly in place of a two fan assembly. This should be done by a Teledyne Paradise
Datacom technician, using the procedure outlined in drawing number 206573.
7.3 Troubleshooting guide
The following section describes solutions for some of the most common issues with the
operation of the Compact Outdoor SSPA.
7.3.1 Unit doesn’t power up
Cooling fans do not spin, and alarm LED lamps are off.
Possible causes: AC power is off; Unit which requires 220V AC operation is being powered
from 110V AC grid; Unit is connected to an inadequate circuit breaker. Unit has no connection
between chassis and earth ground or has inadequate earth ground.
Possible solutions: Check SSPA unit datasheet for AC power requirements. Provide the
specified AC power for the unit. Re-check continuity between unit’s chassis ground and earth
ground. Earth ground connection is required for normal SSPA operation!
7.3.2 Unit powers on, LED lamp glows red
Possible causes: SSPA peripheral alarms (Auxiliary, Spare, Forward RF etc) are set as
Major alarms. Summary Alarm is caused by external reference BUC module.
Possible solutions: Connect to the SSPA unit via the Universal M&C software and disable
peripheral alarms. In the case where the unit is equipped with an externally referenced BUC,
provide the specified reference signal to the SSPA IF input.
68 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
7.3.3 SSPA unit powers up, LED lamp glows green, but no RF output signal is present
Possible causes: The SSPA is muted by an external signal or by an internal setting. The
input RF signal is too low. The input signal is out of band.
Possible solutions: Make sure the J4 connector has a jumper installed between pins B and
V (refer to Table 3-1 or Table 3-2). Connect to the unit via the Universal M&C and set the
Mute setting to Off. Check the input RF signal level and frequency. Make sure the signal
properties are appropriate for the unit.
7.3.4 Cannot connect to SSPA through remote control interface
Possible causes: The SSPA remote control is set to a different interface setting. The
interface cable is not wired properly or has a broken wire harness. A PC interface port
malfunction. An incorrect version of the software is being used to control the unit. The
selected SSPA protocol is no longer supported by the SSPA firmware. In the case of RS232
interface: the wire harness is using the Chassis ground rather then a Com ground pin. In case
of IPNet or SNMP interface: PC ARP cache entry is set for different MAC/IP address pair.
Possible solutions:
a) In the case where SSPA communication settings have been accidentally set to a random
configuration, establish a connection to the unit with a L207755 Quick Start cable in
conjunction with the Universal M&C software (see Section 3.3.2). After establishing a
communication link with the unit, adjust the following settings to the desired configuration:
Serial Network address, Protocol Select, Baud rate (if Normal protocol was set in in the
Protocol configuration), IP address, Subnet, Gateway, IP port and IP lock address (if IPNet
or SNMP protocols were selected), Community Set and Community Get strings (if SNMP
protocol was selected), web password (if IPNet was selected).
Disconnect the Quick start cable, and cycle AC power to the unit with the custom cable
harness plugged into the J4 M&C connector. Recheck custom control link.
b) In the case of a RS232 interface, make sure to use communication ground pin d from the
J4 connector as the RS232 ground. The SSPA RS232 port is electrically isolated from
chassis ground. In order to use the Quick Start cable from previous generations of
Compact Outdoor SSPAs (PN L202151), the cable harness will need to be modified. To
do so, open the MS connector shell and connect the chassis and communication ground
pins together (Pins V and d).
c) In the case of IPNet, use 10Base-T approved cables (CAT5, CAT6) to make a
connection to the unit. Maximum cable length should not exceed 300 ft. Use Figure 3-7 as
a wiring guideline. If an IP connection with custom IP addressing is desired, don’t make
any connection to interface selection pins j and e.
d) In the case of SNMP interface, make sure that the SNMP community strings match
between the SNMP NMS software and the unit. Default values for these strings are: Public
and Private. Connect to the unit via the Universal M&C to check or change string values.
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 69
e) In the case of IPNet or SNMP protocols, clear the PC ARP cache by issuing the
following command in a Windows command line interface: arp –d.
f) Binary and Terminal protocols are no longer supported by Compact Outdoor units. Use
the currently available interfaces instead.
7.3.5 The FSK link between a modem and the SSPB unit is not working
Possible cause: The unit is set to use IPNet or SNMP interface.
Possible solution: Set the SSPB protocol setting field to “Normal” protocol or (and) remove
any connection to SSPB interface select pins j and e on the J4 connector. Reset AC power.

Section 8: Redundant System
Operation
8.0 Redundant System Concepts
The Compact Outdoor Amplifier is capable of operating in a variety of redundant system
configurations. These include 1:1 and 1:2 as well as 1:1 with L-Band Block Up Converters.
The Compact Outdoor Amplifier has a built-in 1:1 redundancy controller, allowing it to be used
in 1:1 redundant systems without a separate external controller. When used in a 1:2
redundant system a separate controller, RCP2-1200, is required. The three most common
forms of 1:1 redundant system are shown in Figures 8-1 through 8-3.
Figure 8-1 shows a standard 1:1 system in which the RF input is transmitted through a
transfer switch along with the output. Using this configuration the standby amplifier carries no
traffic and simply is terminated by a 50 ohm resistive load at its input and by a waveguide
termination at its output.
Figure 8-1: Standard 1:1 Redundant System with input (coaxial) switch
and output (waveguide) switch
With the system configured as in Figure 8-2, the RF input is passed through a microwave
splitter. This keeps ‘live’ traffic on the standby amplifier and is useful for observing the traffic
via the RF sample port on the standby amplifier.
Figure 8-2: 1:1 Redundant System with input splitter substituted for input switch
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 71
The system shown in Figure 8-3 uses the same concept of the power splitter on the RF input.
In this case the Compact Outdoor amplifiers are equipped with L-Band block up converters.
L-Band input amplifiers use phase locked oscillators as the local oscillator to the up converter.
Such systems must use a splitter at the input instead of a switch so that the reference input is
always available to the standby amplifier. If the reference signal is lost the standby amplifier
would report a BUC (Block Up Converter) fault.
Figure 8-3: 1:1 Redundant System with L Band input
Care must be taken when selecting the splitter for an L-Band input system. The splitter must
be a wide band design capable of passing the 10 MHz or 50 MHz reference signal along with
the 950 MHz to 1525 MHz traffic input. The reference frequency power level must be at least
-10 dBm into each Compact Outdoor Amplifier.
72 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
8.1 Compact Outdoor Amplifier in 1:1 Redundancy
The Compact Outdoor Amplifier is ideally suited for a self-contained and cost effective 1:1
redundant system. Each Compact Outdoor Amplifier has a built-in 1:1 redundant controller.
The controller is activated via computer command from the Teledyne Paradise Datacom
Universal M&C application. The Compact Outdoor Amplifier may be purchased as a
redundant system or upgraded in the field from a single thread amplifier to a 1:1 redundant
system.
A redundancy kit may be purchased separately which includes the following components:
• Mounting Frame
• Waveguide Switch / Mounting Bracket
• Input Splitter
• Waveguide bends from amplifier to switch
• High Power Waveguide Termination
• Coaxial cables from splitter to Amplifier input
• Link Cable
• Switch Cable

SSPA SYSTEM
Figure 8-4: Typical 1:1 Redundant System Outline
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 73
8.1.1 Hardware Setup
The hardware setup for a Compact Outdoor 1:1 Redundant System is very simple and
involves the addition of (2) cables along with a redundancy switch. A schematic diagram of
the redundancy setup is shown in Figure 8-5.
Figure 8-5: 1:1 Redundant System with Link Cable and Switch Cable installed
The Link Cable is a simple (3) conductor crossover cable that allows the system to pass
command and control between amplifiers. With the redundancy kit, this cable is supplied in a
26 inch (660 mm) length.
The Switch Cable is a “Tee” configuration and connects between each amplifier and the
redundancy switch. The Redundancy Switch is a -28 VDC type. Therefore the controller in
each Compact Outdoor Amplifier is capable of supplying +28 VDC to the common voltage
input. Either controller may then provide a (sink) return to engage either position 1 or position
2 of the redundancy switch.
Care must be observed when connecting this cable to the amplifiers. The cable end labeled
“A1” must be connected to the amplifier whose output is connected to Port 3 of the waveguide
switch. Likewise the cable end labeled “A2” must be connected to the amplifier whose output
is connected to Port 1 of the waveguide switch. This is for proper identification purposes of
the Redundancy Control Firmware used by each Compact Outdoor Amplifier.
74 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
8.1.2 Software Setup
To instruct the Compact Outdoor Amplifier to operate in redundancy it is necessary to
temporarily connect it to a PC running the Teledyne Paradise Datacom Monitor and Control
Software to set up the redundant configuration. There are three basic modes of Redundant
System communication.
1. Stand-Alone 1:1 Redundant System—No Computer Control
2. PC Control using RS-232 and Paradise M&C Software
3. PC Control using RS-485 and Paradise M&C Software
8.1.2.1 Stand-Alone 1:1 Redundant System
As Method 1 implies, it is possible to have a 1:1 system operate with no PC monitor and
control. Initially, however, it is necessary to connect each amplifier up to a PC to configure it
for redundant operation. Figure 8-6 shows the redundant system with each amplifier enabled
to use RS-232 communication with a PC. Every Compact Outdoor amplifier is shipped from
the factory with a “Quick Start” cable that can be used for this purpose. If the Compact
Outdoor Amplifiers are purchased as a 1:1 Redundant System, this Software Setup
procedure will have been set at the factory and it is not necessary to repeat this process.
Figure 8-6: 1:1 System with RS-232 Communication to each Amplifier
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 75
Each amplifier can be configured for redundancy by the Teledyne Paradise Datacom
Universal M&C software that ships along with each unit. Using the Quick-Start cable, connect
each amplifier to the PC and run the M&C program. Select the “Settings” tab from the main
form. The “Settings” window will appear as shown in Figure 8-7.
1. System Mode: Each SSPA’s System Mode must be set to “1:1 Redundant Mode”
2. Choose a Hierarchical Address for each amplifier. HPA 1 means this SSPA will use
the RF switch position 1 as its On Line state position. HPA 2 will then use RF
switch position 2.
3. Redundancy Startup State: The amplifier which is desired to be on line should be set
“On Line”. The other amplifier should be set as “Standby”.
All settings are valid as soon as the operator sets them on the SSPA Settings window. The
SSPA’s redundant operation can be verified by monitoring the RF Switch Fault indicator as
shown in Figure 8-15.
Figure 8-7: M&C Program “SSPA Settings” window
76 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
The Standby amplifier can be muted to have a “Cold Standby” condition. It keeps the SSPA
module powered down for power savings while the microprocessor and fans remain
operational. SSPAs with Parallel I/O board firmware version 3.50 or beyond are provided with
a true cold standby mode. In this mode, the SSPA will be muted automatically. Cold standby
mode has to be selected through a serial control interface (For details, see Table 10-7, data
address 20).
If the Standby amplifier switches to the Online state, it will automatically un-mute and transmit
traffic. If the operator attempts to mute the Online amplifier a warning message will be
displayed “You are about to mute the Online unit. Proceed with Mute?”
Similarly, connect the second amplifier to the computer’s COM port and perform the 1:1
selections on the SSPA Settings window. Just as with the first amplifier, make sure that the
System mode is set to 1:1 redundant. Select a hierarchical address, HPA 1 or HPA 2 and a
startup state.
The amplifiers may then be disconnected from the computer’s COM port as the Compact
Outdoor Amplifiers’ microcontroller is now programmed for 1:1 redundancy control. It is not
necessary to run the Windows based M&C software with the redundant system. The M&C
software is only a convenience for remote monitoring and control of the redundant system.
The following sections detail the operation of the M&C software in 1:1 redundant system
operation.
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 77
8.1.2.2 PC Control using RS232 and Paradise M&C Software
In applications requiring remote monitor and control of the redundant system, the Teledyne
Paradise Datacom Universal M&C program has a control panel that can be used for this
purpose. To enable the 1:1 system to operate with the remote control software, first configure
each amplifier for 1:1 redundant operation as previously described in the Stand-Alone 1:1
Redundant System section.
When using RS232, a separate COM port will be required for each amplifier. Therefore a
computer with at least two COM ports is required for such a system. Systems using RS232
are limited by the length of the communication cable from the amplifiers to the computer. This
is typically a maximum of 30 ft. (9 m) for most RS-232 device drivers. Systems requiring
longer communication cable links should use RS-485 communication.
After starting the M&C program, select [Action] → [Add Unit] → [Compact Outdoor SSPA].
See Figure 8-8. The Add New SSPA window will appear as shown in Figure 8-9.
Figure 8-8: Adding a SSPA Monitor and Control Window
78 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
Figure 8-9: Add New Compact Outdoor SSPA window
From this screen choose the COM port and baud rate. The factory default baud rate is 9600.
If a single SSPA is used the Global network address setting should be used.
After the COM port has been selected the “Operation” window will be displayed. If the SSPA
is connected to a power source and turned on, the SSPA will begin communicating with the
M&C program and its operating parameters will be displayed, as shown in Figure 8-10.
Figure 8-10: Individual SSPA Operation Window
Go back to the “Add New Local SSPA” window and select the correct COM port for the
second amplifier. Its operation window will appear on the M&C program display. If either of
the amplifiers is not communicating with the M&C Operation screen, debug the system to find
the problem. Check the RS-232 connection from each amplifier to the appropriate COM port
of the PC.
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 79
Once reliable communication has been established between each amplifier and the computer,
the Redundancy Control Panel can be displayed. From the M&C program’s main window,
choose [Action] → [Internal Redundant System] → [1:1 Compact Outdoor SSPA System].
See Figure 8-11.
Figure 8-11: Universal M&C, Add Unit Menu Tree
The Redundant Control Panel window will then be displayed as in Figure 8-12. Note that
once the Redundant Control Panel is enabled, the Main Menu on the M&C program changes.
Figure 8-12: Universal M&C, Add 1:1 Redundant System Window
The Control Panel must be configured by selecting “Set Redundancy System” and choosing
an amplifier for SSPA 1 and SSPA 2. Either amplifier may be designated as SSPA 1 or
SSPA 2. Each amplifier is identified by its ID number. The ID number is a fixed number and
cannot be changed. It is a unique encoded value determined by the particular amplifier’s
model number and serial number. If the ID number is forgotten, refer to the System Watcher
window. This window continuously displays which amplifier, by ID number, is connected to
each specific COM port. After the Control Panel has been configured the display will change
to the view shown in Figure 8-13.
80 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
Figure 8-13: Universal M&C, showing a configured 1:1 Redundant System
From the Control Panel display all typical 1:1 system functions can be monitored and
controlled. A particular SSPA can be put on line be selecting the command button for either
amplifier. The online amplifier will be indicated by the “Online” notation. The standby amplifier
will be listed as such as shown in Figure 8-13 (Unit 2).
A particular redundant configuration can be saved by going to the “File” menu and selecting
“Save Configuration”. Thus if the program is terminated and then restarted, it will immediately
boot up with the Redundancy Control Panel display.
Each individual amplifier’s characteristics can still be monitored and controlled from its
respective “Operation” window. If the user attempts to Mute an on-line amplifier, a warning
window will pop-up asking if this is a valid request. See Figure 8-14.
Figure 8-14: Dialog window, Affirm mute of on-line amplifier
Operations Manual, HPA2, Compact Outdoor SSPA 208495 REV C 81
If the online amplifier enters a fault condition, the redundant switch will automatically route the
signal to the Standby amplifier. The faulted amplifier will be colored red in the Redundancy
Control Panel display. See Figure 8-15.
Figure 8-15: Control Panel showing Unit 1 faulted and signal routed to Unit 2
By clicking on the [Unit1] button (which will be labeled to correspond to the unit’s name), the
M&C Status window for Unit1 is activated, so the user may determine the cause of the fault.
See Figure 8-16. Once the fault is cleared, Unit1 can be reactivated as the online unit by
clicking on the triangular amplifier symbol for Unit2 in the System1 control panel.
Figure 8-16: Unit1 Status panel showing Summary and Temperature Faults
If the redundant switch is manually rotated to the offline amplifier in a redundant system, an
RF switch fault will occur. The system will not attempt to switch back to its original position.
On the Redundancy Control Panel, both amplifiers will be colored red. The switch must be
manually rotated back to the online amplifier.
82 208495 REV C Operations Manual, HPA2, Compact Outdoor SSPA
8.1.2.3 PC Control using RS-485 and Paradise M&C Software
Applications requiring long cable runs between the computer and the 1:1 Redundant System
may use RS-485 communication. The Compact Outdoor Amplifier’s firmware supports
networking on a RS-485 bus. This type of network can be used to support the 1:1 Redundant
System.
The RS-485 link can typically be run up to 4000 ft. (1200 m) lengths. A good quality twisted
pair cable should be used along with proper line terminations. There are no parallel end
terminations in the amplifier’s RS-485 interface. Any required cable terminations have to be
added externally. Either full or half duplex RS-485 communication is supported. Schematics
showing the proper wiring of each version are shown in Figures 8-17 and 8-18.
As in the stand-alone redundant system of Section 8.1.2.1, each Compact Outdoor SSPA
must be programmed for Redundant System operation by using the RS-232 interface and
M&C program. Similarly when networking SSPAs on a RS-485 network, each amplifier’s
address must be set before they can communicate over the network. Both of these steps
should be performed together as part of the initial system setup.
Figure 8-17 shows a typical 1:1 Redundant System with RS-485 Full Duplex Communication.

8.2 1:2 Redundant Systems
The Compact Outdoor Amplifier can also be configured in 1:2 Redundant Systems. The major
difference being that the amplifier’s internal controller can not be used for system control.
Instead a separate RCP2-1200 Redundant System controller is used to provide system
control. The controller can be remotely located from the amplifiers up to 500 ft. Figures 8-19

8.3 1:2 Redundant Systems with L-Band Input
The 1:2 Redundant System with L Band Input can be configured with internal Block Up
Converters that contain internal 10 MHz reference oscillators or configured for use with an
external 10 MHz reference source. Systems configured with internal 10 MHz reference are
straightforward extensions of the basic 1:2 architecture. Because the 10 MHz reference is
integral to the converter there is no possibility of an interruption of the 10 MHz during
switchover. Furthermore the standby amplifier always has 10 MHz reference and will not be
faulted. Such a system is shown in Figure 8-23.

The Block Up Converters used in Satcom equipment typically use some form of phase locked
local oscillator in the converter architecture. The Block Up Converter will signal an alarm
condition whenever the oscillator looses phase lock. The amplifier will go into a mute state so
that no spurious (off frequency) emissions can be transmitted to the satellite. The alarms from
the BUCs and SSPAs are sent to the RCP2-1200 system controller which determines the
proper switch conditions for the system.

A special case of the 1:2 Redundant System exists when an external reference is
required of the system. With an external 10 MHz reference input on each polarity input to the
system, the standby amplifier will not receive a reference signal and therefore would be in a
faulted condition. In this state, the redundant controller will not allow the standby amplifier to
come on line if a failure occurs with amplifier #1 or amplifier #3. See Figure 8-24.

At first it may be thought that a 10 MHz signal could be injected into the normally terminated
port of the input switches. While in a normal operating state with all three BUCs operational
this would work fine. However in the event of a failure of one of the on-line units, the 10 MHz
would also be interrupted to the standby unit, as shown in Figure 8-25. Due to the quick
determination of a unit fault, the controller will interpret a fault on the standby amplifier and
reliable switchover can not be guaranteed.
To overcome the problems that result from interruption of the 10 MHz reference, it is
imperative that the reference be injected in the system after the waveguide switches. One
technique could be to install a multiplexer on the input of each amplifier that would allow the
injection of the 10MHz reference. In this case a separate 10 MHz line would have to be run to
the system and a three way splitter could distribute the reference to each amplifier.
The standard Teledyne Paradise Datacom configuration overcomes this issue by using a
Reference Combiner assembly.

Figure 8-26: Standard 1:2 Redundant System with External 10MHz Reference
using the Reference Combiner Assembly.
The Reference Combiner assembly couples a sample of the 10 MHz reference from each of
the two polarity inputs. It will then supply the standby amplifier with the reference from either
of the two inputs. The reference combiner will arbitrate and decide which 10 MHz signal to
supply to the standby amplifier. It will not supply both 10 MHz sources to the standby
amplifier. This allows all three amplifiers to be in a normal operating (non faulted) condition
and the RCP2-1200 controller can operate the system in normal 1:2 redundancy. This eliminates the need for a separate 10 MHz line going to the system as the 10 MHz reference normally exists on each L-Band cable. See Figure 8-26.
Amp 2 is meant to be the standard stand-by amplifier in this configuration. Should Amp 1 or
Amp 3 fault, the RCP2-1200 will automatically switch to the stand-by Amp 2. However, when
this occurs, this interrupts the 10 MHz reference to the faulted Amp/BUC, which results in a
constant BUC fault on that thread. In order to return Amp 2 to the stand-by state, the user will
need to clear the fault, switch to manual mode on the RCP2-1200 and then select Amp 2 as
stand-by. Table 8-1 gives a step-by-step guide to returning Amp 2 to stand-by status.

Section 9: Fixed Phase Combined
Redundant Systems
9.0 Phase Combining Overview
Phase combining amplifiers has long been a popular means of increasing the output power of
an amplifier system. Under high power microwave conditions it is common to utilize some
form of waveguide hybrid coupler to combine the output power of two amplifiers. This coupler
is generally a waveguide tee such as a four port magic tee. On the input side, common
coaxial power splitters can be utilized to divide the power due to the lower power levels at the
input of the system.
Figure 9-1 shows a typical block diagram of a phase combined amplifier pair. As long as the
electrical delay, phase and amplitude of the two paths are kept within close tolerance of each
other, the output power of the system will be twice the output power (+3dB) of a single
amplifier.
Figure 9-1: Phase Combined Amplifier System
The main drawback of this approach is that in the event of an amplifier failure, the total output
power decreases by 6 dB, or a factor of 4. This does not offer the system much in the way of
redundant capability with such a large decrease in output power capability. The power
decrease is due to the fact that with only one amplifier active, the output combiner acts as a
power divider. The output power from the remaining amplifier is divided between the output of
the system and the terminated port of the hybrid combiner. Thus only one half of the power
from one amplifier reaches the output port which is 6 dB less than the combined output power
from both amplifiers.
A high power system requiring a degree of redundancy needs some means of bypassing the
combiner in the event of an amplifier failure. This would allow the full output power capacity
of the remaining amplifier to reach the output. In this case the total RF output power would
only decrease by 3 dB from the phase combined output power. A 3 dB reduction in output
power is generally more tolerable to a system’s link budget thereby giving the system a
degree of redundancy.

Figure 9-2: 1:1 Fixed Phase Combined System with FPRC-1100 controller
A technique has been developed which accomplishes phase combining and provides
redundancy with two waveguide transfer switches. A block diagram of such a system is
shown in Figure 9-2.
This type of system is sometimes referred to as a “Fixed Phase” combined system to
differentiate it from the Variable Phase Combiner (VPC) systems commonly used with
TWTAs. In the 1:1 Fixed Phase Combined system, the waveguide switches allow the
amplifier outputs to either be directed into the combiner or bypass the combiner and connect
directly to the RF output.
Teledyne Paradise Datacom has developed a series of controllers that greatly enhances the
operation of the phase combined system. The FPRC-1100 Phase Combined System
Controller is designed specifically to control 1 for 1 Fixed Phase Combined redundant
amplifier systems. The FPRC-1200 Phase Combined System Controller allows remote control
of 1 for 2 Fixed Phase Combined redundant amplifier systems.
Each controller can be used in either manual or automatic mode to monitor the system
amplifiers for faults and operate the transfer switches. The controller has a very user friendly
interface that allows the operator to monitor the composite output power of the system and
adjust the gain of the amplifiers in 0.1 dB increments over a 20 dB range. The controller
adjusts each amplifier in the system and keeps the amplitude of each balanced for optimal
power combining. To the operator, the system appears as a single amplifier. The operator
can choose between using the system as a phase combined system or a traditional
redundant system.

9.1 1:1 Fixed Phase Combined System Components
An outline drawing of a 1:1 Fixed Phase Combined Amplifier assembly is shown in Figure
9-3 on the following page. The system consists of:
(1) Amplifier Base Assembly, which comprises:
(1) Mounting Base (Frame or Plate)
(2) Compact Outdoor SSPAs
(1) Waveguide Switch Assembly
(1) Signal Box Assembly
(2) Cable Assemblies between SSPAs and Signal Box
(1) FPRC-1100 1:1 Phase Combined Redundant Controller
(2) Cable Assemblies between Signal Box and FPRC-1100
(2) AC line cables
(1) Quick Start RS-232 Cable for test / debug
The Amplifier Base Assembly is typically shipped intact. Verify that the hardware is securely
tightened for each Compact Outdoor amplifier and make sure to observe the amplifier’s
position indicator. If facing the RF Output end of the amplifiers, HPA #1 should be on the left
hand side and HPA #2 should be on the right hand side as shown in Figure 9-3.
Verify that the connections of the Waveguide Switch Assembly mate with the proper SSPA.
9.1.1 Signal Box Assembly
The Signal Box Assembly contains the RF input isolator and splitter that routes the RF to
each amplifier. It also routes the monitor and control signals from each amplifier back to the
FPRC-1100 system controller.
The signal box also contains a phase shifter. This phase shifter is in cascade with the RF
input to HPA #1. This allows the system to achieve optimum power combining and is factory
set for optimum combining across the full bandwidth of the amplifier. It should not normally
require adjustment in the field unless and amplifier has been replaced.

9.2 1:1 Fixed Phase Combined System Operation with the FPRC-1100
Under normal system operation, both HPA #1 and HPA #2 are on-line. Their output power is
combined at the magic-tee waveguide combiner. The waveguide combiner has an integral
RF sampler that provides a sample of the RF output sample at -40 dBc. This port feeds an RF
attenuator/diode detector combination. The detector’s output voltage is sent back to the
Signal box via a coaxial cable and linked to the FPRC-1100 Redundant Controller.
The FPRC-1100 is a 1 RU high indoor controller that can remotely monitor and control the 1:1
Fixed Phase Combined system. The controller has a very user friendly interface that allows
the operator to monitor the composite output power of the system and adjust the gain of the
amplifiers in 0.1 dB increments over a 20 dB range. The controller adjusts each amplifier in
the system and keeps the amplitude of each balanced for optimal power combining.
The FPRC-1100 can be used in automatic or manual mode. In manual mode if a fault occurs
in one of the amplifiers, a fault will be indicated on the front panel but no waveguide switch
change will occur. In automatic mode the controller will determine the appropriate waveguide
switch positions and switch the remaining two amplifiers on line. This will ensure that the
system is operating at full output power capability.
Figure 9-4: FPRC-1100 Phase Combined System Controller
The FPRC-1100 front panel is shown in Figure 8-4. In most cases the user will place the
controller in Auto mode so that the controller can determine the proper switch position in the
event of an amplifier failure. The mimic display shows the position of each waveguide switch
by lighting an LED in the waveguide switch path.
Detailed information on the installation and operation of the FPRC-1100 can be found in the
unit’s operations manual, Teledyne Paradise Datacom drawing #205933.

9.3 1:1 Fixed Phase Combined System with L-Band Input
The basic 1:1 Fixed Phase Combined system topology is very similar to a 1:1 redundant
system and is shown in Figure 9-5. When in Automatic mode, the waveguide switches (SW1
& SW2) either direct each amplifier output to the waveguide phase combiner or, if lower
output power is required, bypass the combiner and send an individual amplifier output to the
system output. The system shown in Figure 9-5 utilizes a redundant controller on the BUCs
in the signal box, along with the SSPA controller to control the phase combining.
HPA1
SIGNAL BOX
HPA2
Figure 9-5: 1:1 Phase Combined System with HPA control of BUC redundancy
A FPRC-1100 controller directs the HPA output switches and monitors the amplifiers. While
the system is operating in phase combined mode and an amplifier enters a fault condition, the
controller will switch the faulted amplifier offline. This provides a soft fail mode and results in a
power decrease of 3dB to the system output power.
The BUC switch (SW3) is driven by an indoor unit RCP2-1100 redundant system controller.
When a fault is detected, the switch is driven to place the faulted BUC offline without user
intervention.
This system may also be operated via manual mode. This mode of operation may offer some
benefits over automatic operation. When in manual mode, the amplifiers will not switch out of
Phase Combined Mode or switch to the operational amplifier without user intervention if an
HPA fault occurs.
However, if a BUC fault occurs, the RCP2-1100 will direct SW3 to place the operational BUC
online. A fault indicator will be present on the front panel of the RCP unit, but the system
output would be unaffected by the fault.

9.3.1 1:1 Fixed Phase Combined System with L-Band Input Components
An outline drawing of a 1:1 Fixed Phase Combined Amplifier with L-Band Input assembly is
shown in Figure 9-7 on the following page. The system consists of:
(1) Amplifier Base Assembly, which comprises:
(1) Mounting Base (Frame or Plate)
(2) Compact Outdoor SSPAs
(1) Waveguide Switch Assembly
(1) Signal Box Assembly with 1:1 Redundant Block Up Converter System

(2) AC line cables

9.3.2 Signal Box Assembly
The Signal Box Assembly contains the Redundant BUC Assembly including the coaxial
switch, the RF input isolator and splitter that routes the RF to each amplifier. It also routes the
monitor and control signals from each amplifier back to the FPRC-1100.
The signal box also contains a phase shifter. This phase shifter is in cascade with the RF
input to HPA #1. This allows the system to achieve optimum power combining and is factory
set for optimum combining across the full bandwidth of the amplifier. It should not normally
require adjustment in the field unless and amplifier has been replaced.
9.3.3 Redundant BUC Operation
With the addition of an RCP2-1100, the BUCs function as an independent, fully redundant 1:1
system that is not affected by the status of the 1:1 phase combined SSPAs.
9.3.4 Adjusting the Phase Combining
The system is phase adjusted for optimum
performance across the frequency band at the
factory, and no adjustments are typically needed
except in the event that a SSPA has been replaced.
The SSPAs are manufactured to a delay specification, but an adjustment may be necessary to
achieve the best operation in the system. After
installing the replacement amplifier, attach a power
meter or spectrum analyzer to the cross-guide
coupler at the output of the system after removing the
