MITSUBISHI RF MOSFET MODULE ELECTROSTATIC SENSITIVE DEVICE OBSERVE HANDLING PRECAUTIONS 440-520MHz 30W 12.5V MOBILE RADIO BLOCK DIAGRAM DESCRIPTION The RA30H4452M is a 30-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 increases substantially. The nominal...
