DESCRIPTION

The RA55H4452M is a 55-watt RF MOSFET Amplifier

Module for 12.5-volt mobile 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 4V (minimum), output

power and drain current increases substantially. The nominal

output power becomes available at 4.5V (typical) and 5V

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.

FEATURES

• Enhancement-Mode MOSFET Transistors

• Broadband Frequency Range: 440-520MHz

• Module Size: 66 x 21 x 9.88 mm

• Linear operation is possible by setting the quiescent drain

current with the gate voltage and controlling the output power

with the input power
