Operations Manual, HPA2, Compact Outdoor SSPA

2.2.1 RF Input (J1) [N-type (F)]

The RF Input connector is a type N female connector. The Compact Outdoor SSPA has a
default maximum nominal gain of 75 dB minimum. Therefore the maximum input signal
required to saturate the amplifier can be calculated as:

Input Power = P

sat

- 75 dB


For example, if a 50 W Ku-Band Compact Outdoor amplifier is used in a system it has a P

sat

=

47.0 dBm. Therefore the maximum input power should be limited to -28 dBm. Slightly higher
input power levels will not damage the amplifier but will result in higher levels of distortion in
the output signal.

WARNING! The maximum input level should be limited to +15 dBm to
avoid damaging the amplifier.


Figure 2-2 shows the input side of the Compact Outdoor Amplifier. This side contains the RF
input (J1), M&C input (J4), and the Interface connections (J5, J6).

2.2.2 RF Output (J2)

The RF Output is brought out through waveguide in the Compact Outdoor Amplifier. Figure
2-3
shows the output of a C-Band Compact Outdoor Amplifier. The Ku-Band amplifiers have a
WR75 grooved flange, while the C-Band and X-Band amplifiers have CPR style grooved
flanges (CPRG-137 for C-Band; CPRG-112 for X-Band). Ka-Band amplifiers utilize a WR28
grooved flange. S-Band units are fitted with Type N (F) connectors at the RF Output.
