High Power C-Band Satellite Terminal External Connections
Rev. 0 2–9
Notes:
1. RF Enable (Pin H connected to Pin R) required to turn the RF Output ON.
Disconnecting the RF Enable pin from the system control pin will cause the
C-Band SSPA to reset. If default parameters must be reloaded, they will not
affect the normal gain of the unit.
2. The Summary Fault contact will be in a NO FAULT condition (Pin D connected
to Pin G), until a C-Band SSPA fault is detected. This is regardless of the RF
Enable input state. When an internal summary fault is detected, the C-Band
SSPA will automatically mute its output. When a summary fault condition clears
the summary fault output, the RF Output will return to the NO FAULT condition
after a RESET (AC power ON/OFF cycle).
3. A thermistor is mounted in order to accurately reflect the temperature of the
C-Band SSPA’s RF components. One lead is connected to Status Common
(Pin G) and the other lead is connected to Thermistor Output (Pin C).
2.1.2.4 RF Output Monitor Port (J4)
This RF interface is used for independent monitoring of the C-Band SSPA’s output
power levels through the use of an external power meter.
2.1.2.5 Prime Power (J5)
The power supply portion of the C-Band SSPA supplies all the internal voltage necessary
to operate the RF section and the Alarm/Interface board. The power supply is configured
for 90 to 265 VAC.

2.1.2.6 RF Output (J7)
Waveguide connection CPR-137R (grooved) is located on the side of the C-Band SSPA.
