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.
