RA45H7687M1

RoHS Compliance, 763-870MHz 45W 12.8V, 2 Stage Amp. For MOBILE RADIO

DESCRIPTION

The RA45H7687M1 is a 45-watt RF MOSFET Amplifier Module for

12.8-volt mobile radios that operate in the 763- to 870-MHz range.

The battery can be connected directly to the drain of the

enhancement-mode MOSFET transistors. Without the gate

leakage current flows into the drain and the nominal output signal

supplied to the gate voltage 1, the output power and the drain

current increase as the gate voltage 2 increases. The output

power and the drain current increase substantially with the gate

voltage 2 around 0V (minimum) under the condition when the gate

voltage 1 is kept in 3.4V. The nominal output power becomes

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 voltages and controlling the output power

with the input power.

FEATURES

• Enhancement-Mode MOSFET Transistors

• Broadband Frequency Range: 763-870MHz

• Metal cap structure that makes the improvements of RF radiation

simple

• Module Size: 67 x 19.4 x 9.9 mm

• Linear operation is possible by setting the quiescent drain current with the gate voltages and controlling the output

power with the input power.

RoHS COMPLIANCE

• RA45H7687M1 is a RoHS compliant product.

• RoHS compliance is indicate by the letter “G” after the Lot Marking.
