Abstract :
A microwave power combining system based on two 15 kW continuous wave magnetrons has been developed and studied. A high power coherent microwave output is required in industrial applications. This system includes two injection-locked S-band 15 kW continuous wave magnetrons. The coherent microwave power combining technique is applied to the experiments. The phase of one magnetron output is controlled by a digital phase shifter, and the phase difference of two magnetron power outputs is monitored by a phase detector. A program is applied to automatically adjusting the microwave power combining process. The experimental combining efficiency is over 96%.
