The RA13H4452M is a 13-watt RF MOSFET Amplifier Module for 12.5-volt mobile radios that operate in the 440- to 520-MHz range. It features enhancement-mode MOSFET transistors, a broadband frequency range, and the ability for linear operation by setting the gate voltage and controlling the input power.
The RA13H4452M is a 13‑watt RF MOSFET amplifier module designed for 12.5‑V mobile 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 document lists electrical characteristics (frequency range 440‑520 MHz, output power up to 13 W, drain voltage 17 V, gate voltage up to 12.5 V), mechanical dimensions (66 × 21 × 9.88 mm), and thermal design recommendations (heat‑sink flatness <50 µm, thermal resistance ≤1.53 °C/W, case temperature <90 °C).
