RA45H4045MR
RoHS Compliance, 400-450MHz 45W 12.5V, 3 Stage Amp. For MOBILE RADIO
DESCRIPTION
The RA45H4045MR is a 45-watt RF MOSFET Amplifier Module
for 12.5-volt mobile radios that operate in the 400- to 450-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.
