Abstract
As an important parameter of traveling wave tubes(TWTs),saturation gain flatness repre-sents the distortion degree of transmitted signal,and the accurate measurement of it has been paid much attention.Point-by-point method and network analyzer method are used to test a Ka-band TWT.It is found that the dual-port calibration cannot completely eliminate the fluctuation of input power,and the test result changes obviously.By improving the test method,the saturation gain flatness is reduced from 0.58dB to 0.12dB,which is close to the result of point-by-point method.The research indicates that the saturation gain flatness test needs to be further calibrated and corrected on the basis of the dual-port cali-bration.关键词
