5.15 5, 10 & 20W 900MHz Power Amplifiers (12-018601, 12-018001 & 12-018002)
5.15.1 Description
These Gallium-Arsenide power amplifiers are Class A 10 & 20W power amplifier from
800-960MHz in a 1 stage balanced configuration. It demonstrates a very high linearity
and a very good input/output return loss. It has built in a Current Fault Alarm Function
with a volt-free relay contact pair as its output.
Its housing is an 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. These amplifiers have no user adjustments and in case of failure should only be
replaced.
