RoHS Compliance, 764-870MHz 45W 12.8V, 2 Stage Amp. For MOBILE RADIO
DESCRIPTION
The RA45H7687M1 is a 45-watt RF MOSFET Amplifier
Module for 12.8-volt mobile radios that operate in the 764- to
870-MHz range.
The battery can be connected directly to the drain of the
enhancement-mode MOSFET transistors. Without the gate
voltage 1 and the gate voltage 2(V
GG1
=V
GG2
=0V), only a small
leakage current flows into the drain and the nominal output
signal (P
out
=45W) attenuates up to 60 dB. When fixed i.e. 3.4V, is
supplied to the gate voltage 1, the output power and the drain
current increase as the gate voltage 2 increases. The output
power and the drain current increase substantially with the gate
voltage 2 around 0V (minimum) under the condition when the
gate voltage 1 is kept in 3.4V. The nominal output power
becomes available at the state that V
GG2
is 4V (typical) and 5V
(maximum). At this point, V
GG1
has to be kept in 3.4V
.
At V
GG1
=3.4V & V
GG2
=5V, the typical gate currents are 0.4mA.
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 voltages and controlling the output power
with the input power.
