DESCRIPTION
The RA45H8994M1 is a 45-watt RF MOSFET Amplifier
Module for 12.8-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 1 and the gate voltage 2(VGG1=VGG2=0V), only a small
leakage current flows into the drain and the nominal output
signal (Pout=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 VGG2 is 4V (typical) and 5V
(maximum). At this point, VGG1 has to be kept in 3.4V.
At VGG1=3.4V & VGG2=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.
FEATURES
• Enhancement-Mode MOSFET Transistors
(IDD≅0 @ VDD=12.8V, VGG1=VGG2=0V)
• Pout>45W, ηT>33% @VDD=12.8V, VGG1=3.4V, VGG2=5V, Pin=50mW
• Broadband Frequency Range: 896-941MHz
• Metal cap structure that makes the improvements of RF
radiation simple
• Low-Power Control Current IGG1+IGG2=0.4mA(typ) @ VGG1=3.4V, VGG2=5V
• Module Size: 67 x 18 x 9.9 mm
• Linear operation is possible by setting the quiescent drain
current with the gate voltages and controlling the output power
with the input power.
