RA30H4552M1 is a 30-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 450- to 520-MHz range.
The RA30H4552M1 is a 30 W silicon RF power module designed for 12.5 V mobile radios operating in the 450‑520 MHz band. It uses enhancement‑mode MOSFET transistors and offers low‑power control current (Ieg≈1 mA) for both non‑linear FM and linear AM modulation.
The datasheet lists maximum ratings, electrical characteristics, typical performance curves, and mechanical dimensions (67 × 19.4 × 9.9 mm). Recommended mounting includes M3 screws tightened to 4.0‑6.0 kgf‑cm and an athermal compound between the module and heat sink. The module is RoHS compliant and includes safety and ESD precautions.
