RA20H8087M

RoHS Compliance,

806-870MHz 20W 12.5V, 3 Stage Amp. For MOBILE RADIO

DESCRIPTION

The RA20H8087M is a 20-watt RF MOSFET Amplifier Module for

12.5-volt mobile radios that operate in the 806- to 870-MHz range.

The battery can be connected directly to the drain of the

enhancement-mode MOSFET transistors. Without the gate voltage

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: 806-870MHz

• 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
