RA45H8994M1 Overview
The RA45H8994M1 is a 45-watt RF MOSFET Amplifier Module for 12.8-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 1 and the gate voltage 2(VGG1=VGG2=0V), only a small leakage current flows into the drain and the nominal output signal (Pout=45W) attenuates up to 60 dB.
