Unpacking and Inspection
Inspect the inside and outside of the shipping container for signs of
damage. If any shipping damage is detected, call the shipping
carrier and submit a damage report.
Unpacking
Compare the packing list to the contents of the container to be
certain that all enclosed material has been received. Save all data
sheets. They will be useful during any maintenance actions. Save
the shipping container and packing material and use it if you need to
reship the unit.
Inspection
Inspect all items for any damage received during shipment. If
shipping damage is detected, submit a damage report to the
shipping carrier. Failure to submit a report may invalidate any future
claims.
Mechanical Installation
When performing the procedures in this section refer to the
appendix titled Mechanical Drawings.
Rack Slide Installation
The amplifier is equipped with a pair of drawer slides. These slides
mate with a pair of cabinet slide assemblies mounted in a standard
19-inch rack (cabinet).
The chassis slide assemblies are mounted to the cabinet with
adjustable mounting brackets.
Note
Two chassis slide assemblies, four mounting brackets, four
nutplates, and mounting screws are supplied with the amplifier.
The specific installation details are dependent upon the cabinet
design. Two front mounting brackets (3 inches long) and two back

mounting brackets (9 inches long) are supplied. See appendix titled
Mechanical Drawings for specific mounting instructions pertaining to
your amplifier.
Waveguide Connection
Caution
Do not overtighten the waveguide mounting screws.
Overtightening may strip the threads in the waveguide
flange. Failure to comply could result in equipment
damage.
Achtung
Ziehen Sie die Halteschrauben des Hohlleiters nicht
zu fest an. Zu festes Anziehen kann das Gewinde am
Flansch des Hohlleiters beschädigen. Nichtbeachtung
dieses Hinweises kann zu Schäden am Gerät führen.
The RF input waveguide (where applicable) is located on the front
panel of the amplifier and RF output waveguide port is located on
the rear panel of the amplifier. Ensure that the proper matching
waveguide flange is used to connect the amplifier input and output
to the RF load.
Refer to Figure 1 , Typical 4 Screw Mounting Flange Tightening
Sequence or Figure 2 , Typical 8 Screw Mounting Flange Tightening
Sequence, for the proper tightening sequence on the flange types
installed on your amplifier.
Caution
When not connected to the external waveguide
system or a terminated load, waveguide flanges
should be covered with a protective cap or tape that
does not leave glue residue when removed. Xicom
recommends the use of Kapton® tape, 3M Brand,
#92, Xicom P/N 602-0001-001. Remove tape or cap
prior to final installation. Failure to comply could result
in contamination to the internal waveguide system or
TWT and equipment damage.

Unpacking and Installation, Rack SSPA
Vorsicht
Wenn die Flansche des Hohlleiters nicht mit einem
externen Hohlleitersystem oder einem Lastanschluss
verbunden sind, sollten diese mit einer
Schutzkappe oder einem Band abgedeckt werden,
das bei der Entfernung keine Kleberückstände
hinterlässt. Xicom empfiehlt die Verwendung von
Kapton® Band, Marke 3M, #92, Xicom P/N 602-0001-
001. Entfernen Sie das Band oder die Kappe vor der
endgültigen Installation. Nichtbeachtung kann zur
Verunreinigung des internen Hohlleitersystems oder
des TWT führen und Schäden am Gerät zur Folge
haben.
Use the following procedure to install the waveguides on your
amplifier.
1. Position the interconnecting waveguide flange with the
amplifier waveguide flange. Make sure that the flanges can be
mated without strain or torsion.
2. If the two flanges cannot be properly aligned or if the
installation is subject to vibration, a flexible waveguide section
should be utilized to eliminate potential strain on the waveguide
connection.
3. Insert any necessary gaskets and windows between the two
flanges.
Note
If the connecting waveguide is to be pressurized at
greater than 5 PSI, a waveguide window must be
installed at the output flange of the amplifier. Use an
absorptive type gasket to preclude radiation leakage.
4. Start by hand tightening all waveguide mounting screws.
5. Tighten all mounting screws with the appropriate size Allen
wrench.
6. Use a sequential tightening procedure. Proceed as follows:
•Partially tighten one of the screws (#1).
•Move the tool to the screw that is diagonally opposite to
the screw tightened in step 1 (#2) and partially tighten that
screw.
•Move clockwise to the next screw to be tightened (#3) and
partially tighten that screw.

MNC-0300-021 8 of 20 Revision D
Unpacking and Installation, Rack SSPA
•Move to the screw diagonally opposite screw #3 and
partially tighten that screw (#4).
•If required, repeat this process for the remaining screws
(#5-#6, #7-#8).
•When you reach the first screw tightened in this step (#1)
increase the torque on the screw and repeat the process
until the screws have all been tightened to the correct
torque.

Unpacking and Installation, Rack SSPA
Air Ducting Installation
The SSPA is cooled with a built-in fan. Heated exhaust air should
not be recirculated into the SSPA. The air intake is located on the
front of the SSPA, and an exhaust fan pulls air through the SSPA. A
clearance of 6-8 inches from the exhaust is recommended to allow
the heated exhaust air to clear the SSPA.
If the unit is installed in a closed cabinet or in a configuration that
would tend to recirculate the exhaust air, provisions should be made
to isolate the exhaust air from the intake air supply.
The Exhaust Port Guard can be removed and replaced with an air
duct to carry the exhaust away from the SSPA. The air duct is
available from XICOM Technology. See appendix titled Mechanical
Drawings.
RF Sample Port (Optional)
The RF Sample port (Type N Female Connector) provides a sample
of the RF Output Signal. There is a calibration label above the port
that provides the calibration factors of the sample port.
Refer to the Appendix titled Product Specifications to optional RF
Sample Port configurations.

Rear Panel Interfaces
The rear panel (Figure 3) has all the connections required to use the
SSPA. Not all of the connections are used in every configuration. The rear
panel connections are:
•RF Output
•Waveguide Switch
•Auxiliary Interface
•COM1
•COM2
•Ethernet
•RF Input
•Prime Power Input
The AC Power Switch turns the AC power ON or OFF. If the AC power is
ON, the Power Supply AC ON Indicator Lamp will be lit.
The Amplifier ON Indicator LED on the power supply shows whether the
Power Switch on the front panel is ON or OFF. If the LED is lit, the front
panel power switch is ON and the DC output of the power supply is being
applied to the amplifier.

RF Output (J9) Waveguide Flange
There are two waveguide flanges available. One for the C-Band SSPA
and one for the Ku-Band SSPA. Table 1 lists the waveguide flanges.
Waveguide Switch (J3) (DB-25 Socket)
The Waveguide Switches shown in Table 2 are recommended for use in a
redundant system.
The waveguide switch connects the built in controller to two SSPAs and
the Transfer Switches in a redundancy configuration. Table 3 lists the
switch connector pinouts.

Auxiliary Interface Connector
The Auxiliary Interface provides these interfaces for the use of the
customer:
•Two sets of Form “C” Relay contacts for Summary Fault
Indication
•External Interlock Input
•RF Inhibit Input
•24 VDC @ 100mA maximum
•±15 VDC for monitoring purposes only.
The pinout of the Auxiliary connector is shown in Table 4 on
page 17,.
External Interlock
The External Interlock (Pin 13) must be shorted to the External
Interlock Return (Pin 11) for the amplifier to operate. Removing the
short causes an External Interlock fault and turns transmitter OFF.
RF Inhibit Control
RF is inhibited when RF Inhibit (Pin 12) is connected to Ground (Pin
9 or optionally, pin 10). The amplifier inhibits RF by removing the
bias voltage to the SSA, thereby eliminating the RF drive to the
SSA.
The amplifier can be factory configured on customer request to
inhibit RF when the connection to ground is removed.
Figure 4 shows the pin layout and Table 4 lists the pin definitions,
functions, and comments for the Auxiliary Interface Connector.

Summary Fault Indicators
Two sets of Form C relay contacts (Summary Fault 1 and Summary
Fault 2) are used to indicate that a fault has occurred.
The Summary Fault 1 indicator signals change state any time an
amplifier fault occurs. The user has the choice of a normally open or
normally closed circuit.
The Summary Fault 2 indicator signals change state any time a
summary fault occurs. The user has the choice of a normally open
or normally closed circuit.
Output Voltage
A + 24 VDC voltage is supplied that can deliver up to 100 mA. This
supply voltage is available on both Pins 1 and 2. The return for this
voltage is either Pin 9 or Pin 10.
