50W 400-2500MHz GaN Power Amplifier

The ZD-PA-400-2500MHz-50W is a multi-octave high-power amplifier operating from 400MHz to 2500MHz, delivering 50W of output power across the entire frequency range. Manufactured using gallium nitride (GaN) and chip-wire interconnect technology, this module ensures superior power performance and an excellent power-to-volume ratio. It is ideal for interference, electromagnetic compatibility (EMC), test, and measurement applications. The module is equipped with over-temperature, over-voltage, and over-current alarms, automatically shutting down in these conditions.

Product Detail

Product Introduction

The ZD‑PA‑400/2500MHz‑50W is a field‑validated multi‑octave high‑power RF amplifier for professional RF integration. Covering 400‑2500 MHz, delivering 50W of output power across the entire frequency range.

Adopting GaN semiconductors and chip‑and‑wire assembly, it features excellent power‑to‑volume ratio and good thermal efficiency. Its compact size fits space‑limited stationary and mobile system builds.

Ideal for signal jamming, EMC evaluation and test‑and‑measurement systems, it sustains consistent performance under long‑term continuous operation in lab or field deployments.

Built‑in monitoring and protection circuits automatically shut down the unit for over‑temperature, over‑voltage and over‑current faults, protecting internal hardware, cutting downtime and extending service life.
