DESCRIPTION The RA45H4452M is a 45-watt RF
MOSFET Amplifier Module for 12.
5-volt mobile radios that operate in the 440- to 520-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 i...
