Its basic application principle and working mode are introduced. Taking a L-band high-power synthesizer as an example, a computer simulation of the CAD technology is performed. The simulation results are compared with the measured results. The results show that the difference between the simulation results and the measured results is less than 0.3 dB, which meets the requirements of the application. Discusses the relationship between the design method and the actual application requirements, and has achieved good results in practical application. This kind of power synthesizer has the characteristics of small insertion loss, good phase balance and amplitude balance, large power capacity, small size and easy assembly and debugging in high power synthesis. It is a good high power synthesis method .
