RoHS Compliance , 806-870MHz 3.6W 7.2V, 2 Stage Amp. For PORTABLE RADIO
DESCRIPTION
The RA03M8087M is a 3.6-watt RF MOSFET Amplifier
Module for 7.2-volt portable radios that operate in the 806 to
870-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 2.5V (minimum), output power and
drain current increases substantially. The nominal output power
becomes available at 3V (typical) and 3.5V (maximum). At
V
GG
=3.5V, 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.
