High Power 25W 2-4GHz CW&Pulsed Integrated PA Module for RF Applications

ZD-PA-2/4G-25W

This 25W power amplifier (2-4GHz frequency range) supports CW&Pulsed input signals, with input pulse width spanning 50ns to CW and RF input drive of 0-3dBm. It integrates multi-layer protections: reverse polarity, over-temperature (power off above 85°C, on below 65°C), over/undervoltage (off above 36V or below 24V), and overcurrent (off above 10A).
Equipped with RS485 for temperature/current monitoring, it features 60dBc non-harmonics spurious, and

The High Power 25W 2-4GHz RF Power Amplifier Module is a high-performance solution tailored for diverse RF scenarios, combining robust high-power amplification capability with smart operational features—though it does not integrate a traditional Digital RF Modulator, it still delivers reliable signal processing. It operates in the 2-4GHz band, providing 44±1dBm saturated output power (≈25W) and supporting both CW and pulsed input signals, with input pulse width covering 50ns to CW and RF input drive of 0-3dBm.
 
It integrates all-around protection: reverse polarity protection prevents damage from wrong wiring, over-temperature protection cuts power over 85°C and resumes below 65°C, over/undervoltage protection shuts down at >36V or
 
RF performance excels: 10dBc second harmonics, >60dBc non-harmonics spurious, and
