Product Summary
The RA13H4047M is a 13-watt RF MOSFET Amplifier
Module for 12.5-voltmobileradios 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
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 at4.5V (typical) and 5V (maximum). At
VGG
=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 bysetting the drain quiescent
current with the gate voltage and controlling the output power with
the input power
