MITSUBISHI RF MOSFET MODULE
RA07H4047M
400-470MHz 7W 12.5V, 2 Stage Amp. For PORTABLE/ MOBILE RADIO
DESCRIPTION
The RA07H4047M is a 7-watt RF MOSFET Amplifier Module
for 12.5-volt portable/ mobile 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.
