DESCRIPTION

BLOCK DIAGRAM

The RA03M8894M is a 3.6-watt RF MOSFET Amplifier

Module for 7.2-volt portable radios that operate in the 889- to

941-MHz range.

The battery can be connected directly to the drain of the

enhancement-mode MOSFET transistors. Without the gate

voltage (V_GG=0V), only a small leakage current flows into the

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

V_GG=3.5V, 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.
