详细介绍:
The RA30H2127M is a 30-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 210- to 270-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.the RF input signal attenuates up to 60 dB. The nominal output power becomes available at 4.5V (typical).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.controlling the output power withthe input power.FEATURES?
