RA13H8891MA is a 13-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 889- to 915-MHz range.
The RA13H8891MA is a 13‑watt RF MOSFET amplifier module designed for 12.5‑V mobile radios operating in the 889‑915 MHz band. It features enhancement‑mode MOSFET transistors, low‑power gate control (≈1 mA at 5 V), and can be used for both non‑linear FM and linear AM modulation.
The document provides maximum ratings, electrical characteristics, typical performance curves, mechanical dimensions, and detailed recommendations for mounting, heat‑sink design, soldering, and ESD protection. Safety and RoHS compliance information are also included.
