| Abstract: | This paper describes the reason of the TWT amplifiers transmitter's nonlinear distortion in phase and amplitude caused by the power ripples,and studies the distortion equation and reduces the equation to a simple one. The paper finally derives the relation between the power ripple amplitude and IF of MTI. The results may serve as quantitative reference in selecting a suitable TWT and deciding the parameters of the power ripple. |
