RA60H3847M1
RoHS Compliance, 378-470MHz 60W 12.5V, 2 Stage Amp. For MOBILE RADIO
DESCRIPTION
The RA60H3847M1 is a 60-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 378- to

470-MHz range.
The battery can be connected directly to the drain of the
2
3
enhancement-mode MOSFET transistors. Without the gate
voltage (VGG=0V), only a small leakage current flows into the drain and the nominal output signal (Pout=60W) attenuates up to 60 dB. The output power and the drain current increase as the
gate voltage increases. The output power and the drain current
increase substantially with the gate voltage around 0V(minimum).
