DESCRIPTION

The RA07M4452M is a 7-watt RF MOSFET Amplifier

Module for 7.2-volt portable radios that operate in the 440- to

520-MHz range.

The battery can be connected directly to the drain of the

enhancement-mode MOSFET transistors. Without the gate

drain and the RF input signal attenuates up to 60 dB. The output

power and drain current increase as the gate voltage increases.

With a gate voltage around 2.5V (minimum), output power and

drain current increases substantially. The nominal output power

becomes available at 3V (typical) and 3.5V (maximum). At

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.
