DESCRIPTION

The RA80H1415M1 is a 80-watt RF MOSFET Amplifier Module

for 12.5-volt mobile radios that operate in the 144- to 148-MHz

range.

The battery can be connected directly to the drain of the

enhancement-mode MOSFET transistors. The output power and

drain current increase as the gate voltage increases. With a gate

voltage around 4V (minimum), output power and drain current

increases substantially. The nominal output power becomes

available at 4.5V (typical) and 5V (maximum). At VGG=5V, the

typical gate current is 1 mA.

This module is designed for non-linear FM modulation, but may

also be used for linear modulation by setting the drain quiescent

current with the gate voltage and controlling the output power with

the input power.
