896-902/ 935-941MHz 20W 12.5V, 3 Stage Amp. For MOBILE RADIO
DESCRIPTION
The RA20H8994M is a 20-watt RF MOSFET Amplifier Module
for 12.5-volt mobile radios that operate in the 896- to 941-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.
