DESCRIPTION
The RA07M4452MSA is a 7-watt RF MOSFET Amplifier
Module for 7.2-volt portable 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 (V_GG=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
V_GG=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.
