The document describes a 13-watt RF MOSFET amplifier module for 12.5-volt mobile radios. The module features enhancement-mode MOSFET transistors, a broadband frequency range, low-power control current, and the possibility of linear operation.
The RA13H4047M is a 13‑watt RF MOSFET power‑amplifier module designed for 12.5‑V mobile radios operating in the 400‑470 MHz band. It uses enhancement‑mode MOSFET transistors and provides up to 13 W output power with a typical gate current of 1 mA.
Key features include a broadband frequency range (400‑470 MHz), low‑power gate control, RoHS compliance, and a compact package (66 × 21 × 9.88 mm). The module can be used for non‑linear FM modulation or linear AM modulation by adjusting gate voltage and input power. Recommended mounting includes a flat heat sink, a tightening torque of 4.0‑6.0 kgf‑cm, and careful ESD handling.
