rf mosfet amplifier power module RA45H8087M

TheRA45H8087M is a 45-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 (VGG=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. 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. Brand name: Mitsubishi Module number:RA45H8087M Frequency range: 806-870MHz Vdd: 12.5V RF POWER MODULE Linear operation is possible by setting the quiescent drain current with the gate voltage and controlling the output power with the inputpower.
