1Watt Low Power Amplifier (11-007901)
5.4.1 Description
This amplifier is designed as a 1.0 W driver from 380 MHz to 470 MHz for the 10W output
amplifier. It is a 2 stage amplifier where each stage is in balanced configuration. It
demonstrates very high linearity and good input/output VSWR. There is a Current Fault
Alarm Function, which indicates failure of each one of the RF transistors by various alarm
output options. The amplifier is housed in an aluminium case (Alocrom 1200 finish) with
SMA connectors for the RF input/output and a 9way D-type connector for DC and alarm
outputs.
