2 kW continuous wave power combining technique in S band

This paper introduces the 2 kW continuous wave power combining technique based on TWTs. It mainly proceeds the analysis of the combining efficiency and the factors influencing the conformation of magnitude and phase. A 2 kW power amplifier is designed based on the analysis. The magnitude equalizing, phase equalizing and combiner protecting are also discussed. The experiments indicate that the combining efficiency can be greater than 95% with magnitude and phase equalizing technique.
