• Pout>7W @ V_DD=12.5V, V_GG=3.5V, P_in=20mW
• >40% @ P_out=7W (V_GG control), V_DD=12.5V, P_in=20mW
• Broadband Frequency Range: 400-470MHz
• Low-Power Control Current I_GG=1mA (typ) at V_GG=3.5V
• Module Size: 30 x 10 x 5.4 mm
• Linear operation is possible by setting the quiescent drain current with the gate voltage and controlling the output power with the input power

The RA07H4047M is a 7-watt RF MOSFET Amplifier Module for 12.5-volt portable/ mobile radios that operate in the 400- to 470-MHz range.

The battery can be connected directly to the drain of the enhancement-mode MOSFET transistors RA07H4047M. Without the gate voltage (V_GG=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 2.5V (minimum), output power and drain current increases substantially. The nominal output power becomes available at 3V (typical) and 3.5V (maximum). At V_GG=3.5V, the typical gate current is 1 mA.

This module RA07H4047M 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.
