RA07M4047M
RoHS Compliance , 400-470MHz
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 (V
=0V), only a small leakage current flows into the
GG
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
=3.5V, the typical gate current is 1 mA.

GG
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.
