RA30H4452

440-520MHz 30W 12.5V MOBILE RADIO
 
 
DESCRIPTION
The RA30H4452M is a 30-watt RF MOSFET Amplifier 
Module for 12.5-volt mobile radios that operate in the 440- to 
520-MHz range.
The battery can be connected directly to the drain of the 
enhancement-mode MOSFET transistors. Without the gate 
voltage (VGG=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 
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 by setting the drain quiescent 
current with the gate voltage and controlling the output power with
the input power.
 
 
 
FEATURES
• Enhancement-Mode MOSFET Transistors
(IDD@0  @ VDD=12.5V, VGG=0V)
• Pout>30W, hT>40%  @ VDD=12.5V, VGG=5V, Pin=50mW
• Broadband Frequency Range: 440-520MHz
• Low-Power Control Current IGG=1mA (typ) at VGG=5V
• 66 x 21 x 9.8 mm
• Linear operation is possible by setting the quiescent drain 
current with the gate voltage and controlling the output power 
with the input power
