This product is a 6.5-watt RF MOSFET amplifier module for 7.2-volt portable radios operating in the 135- to 175-MHz range. This module can be used 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 RAO7M1317M is a 6.5‑watt RF MOSFET amplifier module designed for 7.2 V portable radios operating in the 135‑175 MHz band. It features enhancement‑mode MOSFET transistors, low‑power gate control (≈1 mA) and a compact 30 × 10 × 5.4 mm package.
The document provides maximum ratings, electrical characteristics, typical performance curves, mechanical construction details, recommended mounting and thermal design, as well as safety and RoHS compliance information.
