User guide

The maximum input level should be limited to +33 dBm to avoid damaging the unit.
RF Output
The RF Output is brought out through waveguide in the Outdoor SSPAs. The Ku Band SSPAs
have a WR-75 Grooved Flange while the C Band SSPAs have CPR style grooved flange
(CPR-137G). An isolator is provided at the output flange with a termination capable of handling
full reflected output power.
Caution should be observed here to make sure that the antenna or a suitable termination
(dummy load) is connected to this port before operating the SSPA The SSPA is protected
against reflection but dangerous levels of microwave energy can be present at this port.
Never look directly into the RF output waveguide.
M & C Connector
The Monitor and Control (M & C) connector is the primary interface point for controlling the
SSPA and monitoring fault conditions. A 10 pin PT02 E12-10P Connector is used at the unit.
A Redundant configured unit may be operated in stand-alone mode, and behaves in a similar
way to a normal Microcontroller equipped unit. If this is done, it is important to cover the
Redundancy Port to protect it from the external environment, since there are live voltages
present on this interface. Never connect anything except for the supplied cables to this
interface port.
