380-470MHz 55W 12.5V, 3 Stage Amp. For MOBILE RADIO
DESCRIPTION
The RA55H3847M is a 55-watt RF MOSFET Amplifier
Module for 12.5-volt mobile radios that operate in the 380- to
470-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 4V (minimum), output
power and drain current increases substantially. The nominal
output power becomes available at 4.5V (typical) and 5V
(maximum). At V
GG
=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.
