RA07M4452M is a 7-watt RF MOSFET Amplifier Module for 7.2-volt portable radios that operate in the 440- to 520-MHz range. It features enhancement-mode MOSFET transistors, broadband frequency range, low-power control current, and linear operation capability.
The RA07M4452M is a 7‑watt RF MOSFET amplifier module designed for 7.2‑V portable radios operating in the 440‑520 MHz band. It uses enhancement‑mode MOSFET transistors and can be driven directly from a battery, with output power controlled by gate voltage or input RF power.
The module is supplied in an H46S package (30 × 10 × 5.4 mm) and includes handling precautions such as ESD sensitivity (down to 1000 V), RoHS compliance, and specific mounting and soldering guidelines to ensure reliability.
