| Abstract: | This paper describes the effects of the TWT amplifiers transmitter's non linear distortion in phase and amplitude caused by the power ripples.Studying the distortion equation and reducing the equaition to a simple one,the paper derives the relation between the power ripple amplitude and IF of MTI.It's the most important that the result provides the useful reference on the theory to select a suitable TWT and decide the parameter of the power ripple. |
