Abstract
Based on several advantages of GaN materials,a method for designing and implementing an X-band 10 kW solid-state transmitter is proposed by using domestic GaN power components.First,the design of the solid-state transmitter is completed,including RF amplification chain,pow-er supply,control protection,cooling,and environmental control.Then,a mismatch synthesis method is used to achieve adjustable output power of the transmitter.The method is easy to imple-ment in engineering,highly reliable,and holds certain reference significance for the design of simi-lar equipment.
