1.0 Introduction
The PowerMAX technology is the preeminent system technology in High Power
Amplifier (HPA) redundancy. PowerMAX is the only purely parallel redundant amplifier
system. All aspects of the system’s active components are parallel redundant including
SSPA modules, monitor and control circuitry, power supplies, and fans. In addition to
being parallel redundant all of the active components are hot-swap removable from
either the front or rear panels. Once installed there is never a need to remove a solid
state power amplifier (SSPA) chassis from the cabinet. All active components are
easily spared on site making the PowerMAX the easiest amplifier system to maintain.
The PowerMAX system architecture is based on a single SSPA module per chassis.
This allows PowerMAX systems to be configured with a large variety of output power
levels. For example, C-Band output power levels range from 400W to 10.0kW.
Furthermore, PowerMAX is a scalable amplifier system. For example, a PowerMAX
system may be initially configured with four modules and later upgraded to eight or 16
modules in the field. There is never a need to return any part of the system to the
factory as the upgrades are easily installed in the field. This provides a tremendous
protection of investment in the amplifier system. The system can easily grow with
future power and bandwidth demands.
1.1 Theory of Operation
PowerMAX is a purely parallel redundant, modular HPA system. It can be populated
with any number of modules between three and sixteen. For maximum RF efficiency it
is recommended to power combine binary arrays of four, eight, or sixteen modules. A
modular system is used either as an extremely high output power amplifier or as a selfredundant amplifier system. Parallel architecture systems make excellent redundant
systems. The PowerMAX system concept is purely parallel throughout all aspects of
the design. The failure of a power supply module, fan, or monitor and control card has
no effect on the system operation. Full output power capability is maintained as well as
remote communications and control of the amplifier system. The system will issue a
minor alarm and indicate precisely which component has failed. The maintenance
technician can then perform the replacement of the failed component without removing
the amplifier from service. This is referred to as hot-swap component replacement.
These components can be replaced without the need to remove an amplifier chassis
from the equipment cabinet.
When used as a self-redundant amplifier system, the PowerMAX should be configured
such that there is one module’s worth of excess output power capacity. In this way a
failure of one SSPA module will still allow the system to provide the minimum output
power necessary. This type of architecture is referred to as n+1 redundant, meaning
that there is one additional RF module then required for normal system operation.
Section 1: General Information
12 214579 REV C PowerMAX SSPA System Operations Manual
When configuring n+1 redundant system output power with binary array systems the
output power guideline shown in Table 1-1 should be followed.
Parallel architecture redundant systems have a distinct advantage over traditional
systems with their absence of transfer switching. Microwave transfer switches used in
traditional redundant systems have an inherent break-before-make characteristic. This
means that there is a finite period of time in which the RF output of the system is
completely dropped. This time can vary between hundreds of milliseconds to seconds
depending on the system design. Many satellite communication links are adversely
affected by a complete loss of carrier even for 100 milliseconds. Because there is no
transfer switch used in the PowerMAX system, there is never a complete loss of output
power for any period of time. The system will only lose a percentage of its output power as shown in the system configuration tables (Tables 1-2, 1-3 and 1-4). Under normal
operation (i.e., when output power levels are a few dB backed off from
maximum output power) there is no noticeable change in operation with a failure of an
SSPA module. The system gain of the PowerMAX will automatically compensate for
the failed module resulting in no change in the operating output power level.
The sophisticated firmware design of the PowerMAX permits the system to operate as
if it were a single chassis amplifier. There is no need to communicate directly with each
individual amplifier chassis, whether operating the system by remote link or locally via
the front panel. The system maintains a hierarchy of control whereby one of the n
modules in a system becomes the master control point. If the master amplifier were to
fail, control is automatically passed on to the next amplifier in the array. The master
amplifier is easily identified in the array by the front panel display.
The firmware design also provides for power savings operation. Any number of the
chassis can be placed in mute mode during periods in which full output power is not
required. This will make significant savings in electricity costs required to operate the
system. Otherwise the system provides 20dB of gain adjustment in 0.5dB increments
as well as optional ALC operation.
The system output power is measured with true rms power detection. Unlike peak
detection circuits common in many HPA systems, true rms detection gives a very
accurate measurement of the system’s output power in the presence of multiple
carriers and modulation types.

1.5 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.
1.5.1 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 non-
essential items.
Operators should never work alone on high voltage de-
vices. 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 115 VAC or 230 VAC entering through the
AC power connector. Caution is required when working near this con-
nector, the AC circuit breaker, or the internal power supply.
1.5.2 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.
HIGH
CUR-
PowerMAX SSPA System Operations Manual 214579 REV C 19
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.
1.5.3 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 trans-
mission 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/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.
1.5.4 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 proper-
ly insulated to Prevent 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.
1.5.5 Tipping Hazard
To avoid risk of bodily injury, follow all instructions for maintaining the stability of the
equipment during transport, installation and maintenance.
RF
SIGNAL
20 214579 REV C PowerMAX SSPA System Operations Manual
The PowerMAX system is designed to be installed on a level
surface. Any attempt to install the cabinet on an uneven surface
may cause the cabinet to tip over, which may result in bodily
injury.
If the system includes the optional cabinet exhaust fans, do not
remove any of the SSPA chassis from the cabinet while the
exhaust fan door is open unless the cabinet is secured to the floor.
1.5.6 High Potential for Waveguide Arcing
As with all systems which utilize high power signals within
waveguide, the potential exists for an electric arc to form.
To minimize this risk, Teledyne Paradise Datacom requires all waveguide be pressurized and dehydrated.
1.6 Waveguide Pressurization and Dehydration
When working with high power amplifier systems that operate into waveguide, the inadvertent creation of arcs is always a concern. An arc in waveguide is the air discharge
breakdown due to the ionization of the air molecules by electrons. This breakdown in
waveguide occurs when the rate of electron production becomes greater than the loss
of electrons to diffusion to the surrounding walls.
It is extremely difficult to precisely predict the power levels at which the breakdown occurs. It is dependent on a variety of factors but the primary factors are:
Waveguide temperature and atmospheric pressure
Components in the Waveguide Transmission System such as: Flanges,
Bends, Tees, Combiners, Filters, Isolators, etc.
Load VSWR presented to the amplifier.
When operating such a high power amplifier system it is imperative that the waveguide
transmission system be dehydrated and pressurized. Operation with an automatic air
dehydrator will provide dry pressurized air to ensure that condensation cannot form in
the waveguide. Also the higher the pressure that can be maintained in the waveguide;
the higher the power handling is in the waveguide system. Most commonly available
air dehydrators are capable of providing pressures of 0.5 to 7.0 psig (25-362 mmHg).
At low power levels (uniform field distribution), low pressure can give good results. For
non-uniform conditions, highly localized breakdown can occur. In this case the wave-
guide system will require much higher pressure. This occurs with bends, waveguide
flange joints. If line currents flow across a small gap introduced by poor tolerances,
flange mismatch, poorly soldered bends, field strengths in excess of that in the main
line can occur in the gap. Pressurization with air or high dielectric gases can increase
the power handling by factors of 10 to 100.
PowerMAX SSPA System Operations Manual 214579 REV C 21
In High Power Amplifier systems an arc will travel from where it is ignited back to the
amplifier. Typical arc travel speed is on the order of 20 ft/sec. Increasing the waveguide pressure can reduce the speed of arc travel. It is difficult to get an accurate calculation of the amount of pressurization needed, but it is a good practice to get as
much pressure as your system can handle. All high power systems that meet the criteria of Table 1-5 are pressure tested at the factory to 1.5 psig. As a guide we rec-
ommend using the power levels in Table 1-5 as the threshold levels w here special
attention be given to dehydration and the overall simplification of waveguide system
design.
It is a common misconception to look up the maximum theoretical power handling of a
particular type of waveguide and assume that this is the maximum power handling.
This may be the case for a straight waveguide tube with ideal terminations but these
values must be significantly de-rated in practical systems. Phase combined amplifier
systems can be particularly sensitive to the potential for waveguide arcing. This is due
to the numerous bends, magic tees, multiple waveguide flange joints, and other wave-
guide components. Table 1-6 shows the power handling capability of some popu-
lar waveguide components normalized to the waveguide power rating. From this table,
we can see how a practical waveguide system’s power handling will de-rate significantly.

Most waveguide systems have many of these components integrated before reaching
the antenna feed. It is not uncommon for a Satcom waveguide network to de-rate to
5% of the straight waveguide power rating.
The load VSWR also has an impact on the breakdown threshold in waveguide networks. Standing waves degrade the power handling of any transmission line network.
The graph of Figure 1-5 shows the rapid degradation of waveguide breakdown vs.
load VSWR. The chart shows that for a 2.0:1 load VSWR, the breakdown potential will
be half of what it would be with a perfectly matched load. This can degrade even more
when high Q elements such as band pass filters are included in the waveguide network.
There are many factors to consider with high power amplifier systems in terms of the
output waveguide network. Especially when using HPA systems with output power
levels of Table 1-5, it is imperative to ensure that the output waveguide network is
pristinely clean and dry. An appropriate dehydrator should be used with capability of
achieving adequate pressure for the system’s output power. Take extra precaution to
make sure that any waveguide flange joints that are not already in place at the factory
are properly cleaned, gasket fitted, and aligned. A properly designed and maintained
waveguide network will ensure that no arcing can be supported and will provide many
years of amplifier service life.

2.1.2.9 Ethernet Port (J9) [RJ45]
This is a RJ45 connector with integrated magnetics and LEDs. This port becomes the
primary remote control interface when the Interface option is selected to “IPNet” as
described in Section 6.6. This feature allows the user to connect the SSPA to a 10/100
Base-T office Local Area Network and have full-featured Monitor & Control functions
through a web interface. See Table 2-5 for Ethernet pin outs.
Note: IP address, Gateway address, Subnet mask, IP port and IP
Lock address needs to be properly selected prior to first use (see Appen-
dix A for details).
LED lamps on the connector indicate network status. A steady Green light indicates a
valid Ethernet link; a flashing Yellow LED indicates data transfer activity (on either the
Transmit and Receive paths).
2.1.2.10 Power Supply M&C/Alarm (J12) [DB9 (M)]
Port J12 is the Power Supply M&C/Alarm connection, which passes information
between a connected N+1 Power Supply and the SSPA. Depending on the system
configuration, the connected cable assembly may include connections to one or more
power supplies. See Section 3.1.8.
