| Abstract: | Based on the L-band 750 W LDMOS power amplifier,a 1200 W solid state power amplifier is realized.The amplifier is composed of power amplifier circuit,water cooling plate,stabilized power supply,control and protection circuit,supporting two working modes of continuous wave and pulse.Through the design of the amplifier circuit,the solid-state power amplifier prototype is made and tested by using three-stage cascade amplification.The test results show that the solid-state power amplifier's operating frequency is 1.3 GHz,bandwidth is±5 MHz,and maximum output power can reach 1300 W.It has the advantages of small volume,inexpensive,stable output power,low phase noise,high harmonic suppression.It can be used in accelerator,microwave heating,internet of things,mobile communication,and other fields. |
