RA07N4452M is a 7.5-watt RF MOSFET Amplifier Module for 9.6-volt portable radios that operate in the 440- to 520-MHz range. The module is designed for non-linear FM modulation, but can 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.
The RAQ7N4452M is a 7.5‑watt RF MOSFET power amplifier module designed for 9.6‑volt portable radios operating in the 440‑520 MHz band. It uses enhancement‑mode MOSFET transistors and provides up to 7.5 W output power when the gate voltage is around 3‑3.5 V and the input power is 20 mW.
The document includes maximum ratings, electrical characteristics, typical performance curves, mechanical dimensions, RoHS compliance, and detailed recommendations for handling, mounting, soldering, and thermal design. Proper ESD protection, heat‑sink flatness (<50 µm), and thermal compound are required for reliable operation.
