RA30H4452M1A
RoHS Compliance, 440-520MHz 30W 12.5V, 2 Stage Amp. For Digital Mobile Radio
DESCRIPTION
The RA30H4452M1A is a 30-watt RF MOSFET Amplifier Module for 12.5-volt digital mobile radios of TDMA that operate in the 440- to 520-MHz range.
The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors. The output power and drain current increase as the gate voltage increases.
At V GG1=3.4V, VGG2=5V, the typical gate currents are 1mA. This module is designed for TDMA, therefore this module separated the gate terminal of each MOSFET to make Ton/Toff time rapid.
