---------------------------------------------- WARNING -----------------------------------------------------
When supplying power to this equipment, connect the accessory 3-pin power connector (with
extension cable) to a 3-pin grounded power outlet. If power is supplied without grounding the
equipment, there is a risk of receiving a severe or fatal electric shock.
In the context of this document any voltage that is lethal is viewed as ‘High Voltage’. Therefore,
even prime power (90 to 265 VAC) is dangerous because prime power potentials have been
known to cause death or injury.
----------------------------------------------- WARNING ----------------------------------------------------
This equipment can not be repaired by the operator. DO NOT attempt to remove the
equipment cover or to disassemble internal components. Only qualified service technicians
should service this equipment. There are high-voltage parts in this equipment presenting a risk of
severe injury to untrained personnel. In addition, there is a risk of damage to precision
components.
----------------------------------------------- WARNING ----------------------------------------------------
ALWAYS TERMINATE THE OUTPUT WAVEGUIDE OF THE POWER AMPLIFIER
WITH AN RF LOAD CAPABLE OF DISSIPATING FULL CW RF POWER. Incorporate
the termination prior to applying prime power to the power amplifier. This procedure prevents
self oscillation and irradiation of the local environment. Even if a source is not connected to the
power amplifier you are working with, there are situations where the power amplifier can go into
a self induced mode and generate high levels of RF energy. Destruction caused under excessive
load voltage standing wave ratio (VSWR) will void the warranty. Although the equipment has
internal protection for VSWR higher than 3:1 and will automatically go in shutdown (with a
delay of 1 second), still it is a safe procedure to avoid unwanted effects.
----------------------------------------------- WARNING ----------------------------------------------------
DO NOT LOOK INTO THE RF OUTPUT PORT OF THE POWERED POWER
AMPLIFIER. Treat the powered amplifier with extreme care. Your eyes are particularly
vulnerable parts of your body.

4. MAJOR SUBSYSTEMS AND THEIR FUNCTIONS
The AWSA-K50-CHE is a Ku-band 50W Solid State Power Amplifier (SSPA). The power
amplifier is intended for mounting near the hub of the antenna. It incorporates DC main power
supply and forced air cooling system, see Figure 1: Product Outline at page 11. The block
diagram of the SSPA is shown in Figure 2 at page 13 and various connectors are shown in
Figure 3 at page 14. The SSPA features a discrete interface for local or remote monitoring via
individual signals as well as interlocking with external devices.
4.1 RF SUBSYSTEM
The RF subsystem contains a power amplifier (driver and power module) designed in Solid State
Technology, waveguide arm assembly and RF input isolation circuit.
The Driver has a gain of 43 dB and an output power (P1dB) of minimum 32 dBm.
The Power module has a gain of 27 – 33 dB and an output power (P1dB) of minimum 46 dBm.
Current consumption is approximately 50A at 12V. A DC board containing the bias, control and
protection circuitry is included in this module. Other functional capabilities are temperature
compensation, high temperature shutdown, and reflected power shutdown.
The Waveguide Arm Assembly includes a harmonic filter, a three-port output circulator and
related power detectors.
• The harmonic filter provides a minimum of 65 dB attenuation of all harmonic products other
than the fundamental signal.
• The output circulator provides one reflected power port coupled via a detector to the Alarm/
Indicate board for reverse power protection. The output port of the waveguide arm assembly
has a minimum 18 dB output return loss and the output flange is WR-75G (grooved).
• One extra sample port, the RF Output Monitor Port, calibrated in coupling ratio versus
frequency, permits the independent monitoring of SSPA output power levels via an ‘N’ type
connector, through the use of external spectrum analyzer or portable power meter.
The RF Input Isolation Circuit provides a minimum Input Return Loss of 18 dB over full
frequency band at the N-type RF input connector of the SSPA.

5. UNPACKINGAND INSTALLATION
This section contains instructions for site preparation, unpacking and installation of the SSPA.
5.1 INITIAL INSPECTION
Inspect the shipping container for damage. If the container or cushioning material is damaged,
immediately contact the carrier that delivered the equipment and submit a damage report. Failure
to do so could invalidate future claims.
5.2 UNPACKING
Carefully unpack and remove all items (inspect the interior of the container for damage). Save all
packing material until all inspections are complete. Verify that all items listed on the packing list
have been received. Inspect all items for evidence of damage in shipment. If damage seems
evident, immediately contact the carrier that delivered the equipment and file a claim. Failure to
do so could invalidate future claims. Check the unit thoroughly for damaged or loose parts. After
visual inspection is complete, proceed to the next step.
5.3 INSTALLATION
Installation of the SSPA includes four phases:
• Mechanical installation
• Electrical installation
• RF connections
• Cooling considerations

5.3.3 RF CONNECTIONS
The following three RF connections are made at the SSPA:
• RF input (J1) – Type-N Female provided at the front panel. User needs Type-N male on
interface connection.
• RF output monitor (J4) – Type-N Female, see Figure 3 at page 14. User needs Type-N male
on interface connection.
• RF Output (J7) - Waveguide connection WR-75 G (grooved). A waterproof gasket is
provided in the shipping kit.
To install the waveguide output flange, proceed as follows:
1. Install the waterproof gasket (supplied) at the output flange of the SSPA.
2. Position the interconnecting flange so that it aligns precisely with the waveguide flange at
(J7).
3. After alignment is verified, loosely attach the interconnecting waveguide to the output
waveguide flange of the SSPA. Start all bolts (supplied) and verify proper alignment before
uniformly tightening the bolts.
4. Carefully tighten all bolts (in opposite pairs rather than sequentially around the perimeter of
the flange) so that the connection is firm. Do not over-tighten because this can strip the
threads or distort the mating flange. Recommended torque is 15 in-lbs for #6-32 bolts.
NOTE: Wrap the mastic tape (provided in the shipping kit) around all connectors in order to
p
revent water/humidity ingress and resultant damage. Squeeze the tape tightly and ensure tha
t
both ends of the tape have formed around the connector and the cable.
CAUTION: Beware of destructive Pin Depth of Mating Connector. When an RF
component connector is mated with a connector having a destructive pin depth, damage will
usually occur to the RF component connector. A destructive pin depth is one that is too long
in respect to the reference plane of the connector. The center pin of the connectors used by
ADVANTECH has a precision tolerance measured in mils (1/1000 inch). The mating
connectors of various suppliers may not be precision types. Consequently, the center pins o
f
these devices may not have the proper depth.

5.3.4 COOLING CONSIDERATIONS
The SSPA is cooled by forced air. The cooling fan is configured for 48V DC operation.
Depending on environmental conditions, the air inlet or outlet openings may become obstructed
by debris, reducing the efficiency of the cooling system. Inspect the unit periodically to ensure
that the grill of the fan intake and all openings on the unit are free of any obstructions.
Insufficient cooling will significantly impact SSPA longevity.
