21.3.1.6 Power Amplifier (12-020804)
This amplifier is a Class AB 40W power amplifier from 860MHz to 960MHz in balanced configuration.
The amplifier demonstrates a very good input/output return loss (RL) and it has a built-in Current Fault
Alarm Function.
The unit 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.
