The SDA3027-150-M is a highly reliable amplifier.It employs ultra-wideband GaN transistors that can output 150 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 ireless communication interference systems in the U,L,and S bands,including but not limited to mobile phones,radiio stations,and drones.

Alarm and Protection:

Parameter	Introductions
Over temperature	When the temperature exceeds 80℃±5℃，the amplifier PIN12 will outputs +5V voltage and the amplifier will automatically shut down; When the temperature drops below 70℃±5℃, the amplifier will automatically turn on.
Over VSWR [note1]	When the output port of the amplifier is open or short,the amplifier PIN13 will outputs +5V voltage and the amplifier shut down,the status will be locked . The alarm state will be cleared once pin 6 transmits a pulse signal
Over voltage [note1]	The amplifier PIN2 will outputs +5V voltage and the amplifier shutdown when the voltage exceeds 32V , the status will be locked. The alarm state will be cleared once pin 6 transmits a pulse signal
