The RA07M4047M is a 7-watt RF MOSFET Amplifier Module for 7.2-volt portable radios that operate in the 400- to 470-MHz range.
The RA07M4047M is a 7‑watt RF MOSFET amplifier module designed for 400‑470 MHz portable radios operating from a 7.2 V battery. It provides up to 7 W output power with a typical efficiency of about 40 % and can be used in both non‑linear FM and linear AM modulation schemes.
The document includes handling precautions, thermal‑design guidelines, recommended mounting hardware, and detailed electrical characteristics. RoHS compliance is indicated by the letter “G” after the lot marking, and the module is sensitive to ESD and high‑temperature stress, requiring careful soldering and heat‑sink design.
