RA20H8994M

896-902/ 935-941MHz 20W 12.5V, 3 Stage Amp. For MOBILE RADIO

DESCRIPTION

BLOCK DIAGRAM

The RA20H8994M is a 20-watt RF MOSFET Amplifier Module

for 12.5-volt mobile radios that operate in the 896- 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 4V (minimum), output power and drain current

increases substantially. The nominal output power becomes

available at 4.5V (typical) and 5V (maximum). At V_GG=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.
