Section 1: General Information
1.0 Introduction
This section provides the general information for the Teledyne Paradise Datacom High Power Outdoor (H-Series) Solid State Power Amplifier (SSPA). This includes a description of the unit and safety precautions.
1.1 Description
The H-Series high power outdoor SSPA contains an internal microprocessor which allows full monitoring and control via a remote serial (RS-232 or RS-485) and Ethernet connector. The microprocessor monitors various voltages, currents and temperatures within the unit for a full fault analysis. The user also has the ability to select additional faults related to the RF output level, an optional reflected RF power level and operating temperature.
An internal attenuator allows up to 20.0 dB of attenuation to be applied to the RF signal. Temperature compensation limits the amplifier’s output response from varying significantly over the operating temperature. Also, the system contains an output sample port.
1.2 Specifications
Refer to the specification sheet in Appendix C for complete specifications.
1.3 Equipment Supplied
The following equipment is supplied with each unit:
• High Power Outdoor SSPA
• Quick Start Cable
• Operations Manual High Power Outdoor SSPA [211670]
1.4 Inspection
When the unit is received, an initial inspection should be completed. First ensure that the shipping container is not damaged. If it is, have a representative from the shipping company present when the container is opened. Perform a visual inspection of the equipment to make sure that all items on the packing list are enclosed. If any damage has occurred or if items are missing, contact:
Teledyne Paradise Datacom LLC 328 Innovation Blvd., Suite 100 State College, PA 16803 USA Phone: +1 (814) 238-3450 Fax: +1 (814) 238-3829
Operations Manual, High Power Outdoor SSPA 211670 REV D 9
1.5 Shipment
To protect the High Power Outdoor SSPA during shipment, use high quality commercial packing methods. When possible, use the original shipping container and its materials. Relia­ble commercial packing and shipping companies have facilities and materials to adequately repack the instrument.
1.6 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.
1.6.1 High Voltage Hazards
High Voltage, for the purpose of this section, is any voltage in excess of 30V. Voltages above this value can be hazardous and even lethal under certain circumstances. Care should be taken when working with devices that operate at high voltage.
• All probes and tools that contact the equipment should be properly insulated to pre­vent the operator from coming in contact with the voltage.
• The work area should be secure and free from nonessential items.
• Operators should never work alone on high voltage devices. There should always
be another person present in the same work area to assist in the event of an emer­gency.
• Operators should be familiar with procedures to employ in the event of an emer­gency, i.e., remove all power, CPR, etc.
• An AC powered unit will have 230 VAC entering through the AC power connector. Caution is required when working near this connector, the AC circuit breaker, or the internal power supply.
1.6.2 High Current Hazards
Many high power devices are capable of producing large surges of current. This is true at all voltages, but needs to be emphasized for low voltage devices. Low voltage devices provide security from high voltage hazards, but also require higher current to provide the same pow­er. High current can cause severe injury from burns and explosion. The following precautions should be taken on devices capable of discharging high current:
• Remove all conductive personal items (rings, watches, medals, etc.)
• The work area should be secure and free of non-essential items.
• Wear safety glasses and protective clothing.
• Operators should never work alone on high risk devices. There should always be
another person present in the same area to assist in the event of an emergency.
• Operators should be familiar with procedures to employ in the event of an emer­gency, i.e., remove all power, CPR, etc.
10 211670 REV D Operations Manual, High Power Outdoor SSPA
Large DC currents are generated to operate the RF Module inside of the enclosure. EX­TREME CAUTION IS REQUIRED WHEN THE ENCLOSURE IS OPEN AND THE AMPLIFI­ER IS OPERATING. DO NOT TOUCH ANY OF THE CONNECTIONS ON THE RF MOD­ULES WHEN THE AMPLIFIER IS OPERATING. CURRENTS IN EXCESS OF 60 AMPERES MAY EXIST ON ANY ONE CONNECTOR.
1.6.3 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 pow-
er density is below recommended guidelines in ANSI/IEEE C95.1. The power den­sity specified in ANSI/IEEE C95.1-1992 is 10 mW/cm2. These requirements ad­here to OSHA Standard 1910.97.
• When a safe distance is not practical, RF shielding should be used to achieve the recommended power density levels.
1.6.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also cause serious safe­ty hazards. The following precautions should be followed when there is a risk of electrical dis­charge:
• Follow all ESD guidelines
• Remove all flammable material and solvents from the area.
• All probes and tools that contact the equipment should be properly insulated to pre-
vent electrical discharge.
• The work area should be secure and free from non-essential items.
• Operators should never work alone on hazardous equipment. There should always
be another person present in the same work area to assist in the event of an emer­gency.
Operators should be familiar with procedures to employ in the event of an emergency, i.e., remove all power, CPR, etc.
1.6.5 High Leakage Current

2.2 Installation of Unit
When installing the H-Series High Power Outdoor SSPA, consider the following:
• There should be at least 8” clearance between the intake fans and any surface, and 8” clearance from the SSPA’s exhaust fans.
• The SSPA should never be enclosed in such a manner that restricts airflow.
• Regular inspection and cleaning of the fans and heatsink is required.
• Normal operating range of the SSPA is -40 to +60 °C.
• The unit will start up in a muted state. To unmute the amplifier, pins V and B of Port
J4 need to be shorted.
A series of mounting holes are located along the sides of the unit that include the lifting han­dles, and on the sides of the unit that include the intake and exhaust fans. If utilizing the mounting holes on the sides that include the fans, ensure the mounting brackets do not inter­fere with the air circulation into and out of the unit.
Warning! The SSPA should never be mounted in such a way that the in-
take fans face up. Doing so will void the warranty.
The H-Series High Power Outdoor SSPA weighs between 100 and 140 lbs. (45.5 - 63.6 kg), depending on the power level of the unit. If mounting the unit to a boom or king post, ensure the mounting brackets and surface are capable of supporting the weight of the unit. At least two persons are required to lift the unit into position for mounting purposes.
See Appendix A for instructions on assembling a mounting frame for a redundant system
installation.

2.3.10 Chassis Ground Terminal
A chassis ground terminal is provided on the intake fan side of the amplifier. A 1/4-20 thread­ed terminal is provided for equipment grounding.
2.3.11 RF Input Sample Port (optional) [Type N (F)]
This is a Type N (F) connector which provides a coupled sample of the RF Input. A calibra­tion label is affixed to the enclosure next to this connector.
2.4 Physical Features
In addition to the I/O connectors, the H-Series High Power Outdoor SSPA features include a summary alarm indicator and removable fan trays.
2.4.1 Summary Alarm Indicator
A summary alarm indicator LED is located on the input side of the amplifier. When the SSPA is operating, this indicator illuminates GREEN. When in a fault condition, it illuminates RED. When an external mute signal is detected, the indicator will blink GREEN if operating, or RED if the amplifier is in a fault condition.
2.4.2 Airflow and Removable Fan Trays
The H-Series High Power 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. The cooling system is based on a forced convection technique in which a series of fans provide the air intake and exhaust.
A minimum clearance of 8 inches (203 mm) should be maintained between each fan tray and any mounting surface. This will ensure that there is no forced re-circulation of airflow from exhaust to intake.
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 7 for instructions on how to clean the fan trays and heatsink. In system configura-
tions, ensure that each unit in the system has sufficient ambient airflow, and adequate space to maintain the fans for each unit.
Spare fan assemblies are available from Teledyne Paradise Datacom. The intake fan assem­bly is part number L213271-1. The exhaust fan assembly is part number L213272-1, and there are two of these per amplifier.
2.4.3 Waveguide Pressure Window (option)
Ku-Band units may be ordered with an optional waveguide pressure window at the RF Output (J2). This option is necessary for installations where the amplifier is connected to a pressur­ized transmission line (up to 15 PSI). All systems include a pressure window.

26 211670 REV D Operations Manual, High Power Outdoor SSPA
3.3.1.2 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 3-6.
Figure 3-6: Fault Indicators
Summary Alarm: The Summary Alarm is simply a logical ‘OR’ of any major alarm indicators. Unit Online: This is a status indicator that illuminates green when the unit is online. External Mute Alarm: The External Mute line gives an indication that the SSPA has been
externally muted by J4-Pin B. This alarm can be configured to trigger a summary alarm if desired. Factory default is to signal a External Mute fault but no summary alarm.
Auxiliary & Spare Alarms: The Auxiliary and Spare Alarms are configurable from the Settings Window. These alarms can be configured to trigger a summary alarm. See Section
3.3.2. Low DC Current Alarm: The Current Fault is factory preset to alarm if the SSPA module cur-
rent falls below 60% of its nominal value. This alarm will also trigger a summary alarm.
Low DC Voltage Alarm: The Voltage Alarm is factory preset to alarm if the SSPA module
current falls below 80% of its nominal value. This alarm will also trigger a summary alarm.
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. This alarm will also trigger a summary alarm.
Forward RF Alarm: The Forward RF Fault Alarm indicates when a the RF output of the am-
plifier falls below the threshold set in the Settings Window.
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. This alarm can be configured to trigger a summary alarm.
Operations Manual, High Power Outdoor SSPA 211670 REV D 27
EEPROM Alarm: The EEPROM Alarm is primarily used as a Fiber RX Link alarm for amplifi-
er units configured with a fiber-optic interface.
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.
3.3.1.3 Voltage, Current and Temperature Display
On the right side of the Status window 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 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 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 25 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 GaN transistors. The Gate Voltage indicator monitors the DC voltage of the gate circuitry of the microwave GaN transistors. These indica­tors provide direct access to the active device operating characteristics.
3.3.1.4 Gain Adjustment
The Gain Attenuation Control is located above the Fault Condition Indicators and below 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 to the right of the displayed value.
3.3.1.5 Forward and Reflected RF Power Indicators
The Forward RF Power is displayed in the central part of the Operation window. This indicator reports the approximate forward 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.
Units with the reflected power meter option also display the Reflected RF Power.
