5.1.6 20W Power Amplifier (12-016301)
5.1.6.1 Description
This amplifier is a Class A 20W power amplifier from 380MHz to 470MHz in a 1 stage
balanced configuration. It demonstrates a very high linearity and a very good input/output
return loss. A built in a Current Fault Alarm Function monitors DC conditions to both
transistor collectors and gives an alarm upon bias change.
Its housing is a machined aluminium case (Alocrom 1200 finish) with SMA connectors
for the RF input/output and a D-Type connector for the power supply and the Current
Fault Alarm Function.
