RoHS Compliance , 400-470MHz 7W 7.2V, 2 Stage Amp. For PORTABLE RADIO
DESCRIPTION The RA07M4047M is a 7-watt RF
MOSFET Amplifier Module for 7.2-volt portable 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 (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 power and drain current increases substantially. The nominal output power becomes available at 3V (typical) and 3.5V (maximum). At VGG=3.5V, the typical gate current is 1 mA. This module is designed for non-linear FM modulation, but may also be used for linear modulation by setting the drain quiescent current with the gate
voltage and controlling the output power with the input power. FEATURES Enhancement-Mode
