The RA07N3340M is a 7.5-watt RF MOSFET Amplifier Module for 9.6-volt portable radios that operate in the 330- to 400-MHz range. It features enhancement-mode MOSFET transistors, broadband frequency range, low-power control current, and the ability for linear operation.
The RAQ7N3340M is a 7.5‑watt RF MOSFET power‑amplifier module designed for 9.6‑V portable radios operating in the 330‑400 MHz band. It uses enhancement‑mode MOSFET transistors and provides up to 7.5 W output power with a typical total efficiency of 43 %. The module can be driven by a gate voltage of about 2.5 V for low power and up to 3.5 V for full output.
The data sheet includes handling precautions for electrostatic discharge, RoHS compliance details, and recommended mechanical mounting. A flat heat‑sink with a thermal resistance of about 3.23 °C/W and a tightening torque of 1.8‑3.0 kgf‑cm are advised. Wiring, soldering, and defluxing guidelines are also provided to ensure reliable operation.
