DESCRIPTION The RA07M3843M is a 7-watt RF MOSFET Amplifier Module for 7.
2-volt portable radios that operate in the 378- to 430-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 2.
5V (minimum), output...
