DESCRIPTION The RA07H4047M is a 7-watt RF MOSFET Amplifier Module for 12.
5-volt portable/ mobile radios that operate in the 400- to 470-MHz range.
The battery can be connected directly to the drain of the enhancement-mode MOSFET
transistors.
Without the gate voltage (V GG=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 2.
5V (minimum), output power and drain cu...
