High Power 25W 4-8GHz CW&Pulsed Integrated PA Module with RS485 Monitoring for RF Applications

This high‑performance rf power amplifier module, compact pa module, is a high‑power 4‑8ghz power amplifier that functions as a reliable cw pulsed power amplifier for multiple RF engineering scenarios. It supports CW and pulsed input signals with pulse width from 50ns to CW, accepts 0‑3dBm RF input drive and provides saturated output power up to 44±1dBm. It delivers excellent RF performance with max flatness ±2dB, gain flatness <3dB, second harmonics >10dBc and non‑harmonic spurious >60dBc. 50‑ohm input and output impedance, both input and output VSWR are less than 1.5:1. This robust pa module is equipped with comprehensive protections: reverse polarity, over‑temperature, over‑voltage, under‑voltage and over‑current protection. It provides TTL on/off control within <10μs and RS485 serial port for real‑time temperature and current monitoring. Working at 28V/3.2A, dimension 120×80×20mm, weight ≤1kg, operating temperature ranges from ‑40℃ to +60℃. This durable rf power amplifier module fits RF test platforms, wireless transmitters and other RF system projects.
