3.6.5.6. 5W Power Amplifier (12-018601)
This amplifier is a Class A 5W power amplifier from 800MHz to 960MHz in a 1 stage balanced
configuration. It demonstrates a very high linearity and a very good input/output return loss (RL). It
has built in a Current Fault Alarm Function.
Its housing is an aluminium case (Iridite NCP finish) with SMA connectors for the RF input/output and
a D-Type connector for the power supply and the Current Fault Alarm Function.
