The RA07M4047MSA is a 7 watt RF MOSFET Amplifier Module for 7.2-volt portable radios that operate in the 400- to 470-MHz range.
The RAQ7M4047MSA is a 7‑watt RF MOSFET power amplifier module designed for portable radios operating in the 400‑470 MHz band. It uses enhancement‑mode MOSFET transistors and can be powered directly from a 7.2 V battery. Output power is controlled by gate voltage, with nominal power available at about 3 V (typical) to 3.5 V (maximum).
The module is built on an alumina substrate with a copper flange, protected by a plastic cap. It requires careful handling to avoid mechanical stress, ESD, and improper soldering. Recommended mounting includes a flat heat sink with a thermal resistance of about 2.8 °C/W and a tightening torque of 1.8‑3.0 kgf‑cm for the M2.6 screws. The device is RoHS compliant and includes safety warnings for high‑frequency power generation.
