RA45H4047M
RoHS Compliance , 400-470MHz
DESCRIPTION
The RA45H4047M is a 45-watt RF MOSFET Amplifier Module for
12.5-volt 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
(V
=0V), only a small leakage current flows into the drain and the RF
GG
input signal attenuates up to 60 dB. The output power and drain current
increase as the gate voltage increases. With a gate voltage around
4V (minimum), output power and drain current increases substantially.
The nominal output power becomes available at 4.5V (typical) and 5V
(maximum). At V
=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.
