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 conneed direly to the drain of the
enhancement-mode MOSFET transistors. Without the gate
voltage (VGG=0V), only a small leakage current flows into the
drain.the RF input signal attenuates up to 60 dB. The output
power.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).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.
