300W 100-500MHz Power Amplifier Module

This 100-500MHz high-power PA module runs on 32V DC with typical 300W output and 58dB max gain, gain flatness ≤7dB. Equipped with dual XT60 power ports and RS485 monitoring, it supports real-time RF power, temperature, voltage and current reading. With SMA input and N-type output, it works steadily at -40℃~+55℃ for low-frequency RF transmission and testing.

Product Detail

This 100-500MHz RF power amplifier module is powered by 32V DC with typical 300W CW output and operating current of 28~32A, delivering 22% average efficiency at full power. It features 58dB maximum gain, gain flatness ≤7dB and input VSWR ≤2, with maximum safe input power up to 10dBm. Equipped with two parallel XT60PW-M power connectors and RS485 communication port for real-time monitoring of voltage, current, temperature and RF output power. With SMA RF input and N-type output, it measures 300×260×30mm and weighs 3.4kg, operating reliably from -40℃ to +55℃, widely used in low-frequency RF testing, signal transmission and EMI simulation systems.
