A325

The SDA3027-200-M is a highly reliable amplifier.It employs ultra-wideband GaN transistors that can output 200 watts of power within the 300MHz to 2700MHz frequency range while maintaining relevant RF performance.In contrast to traditional CW amplifiers,this amplifier can amplify spread-spectrum signals,with an instant bandwidth of up to 200 MHz. When paired with the appropriate SDR digital excitation source,it can produce excellent interference effects on remote control ,data transmission,and positioning signals.Therefore,this amplifier is particularly suitable for use in wireless communication interference systems in the U ,L,and S bands,including but not limited to mobile phones,radiio stations,and drones.
