Abstract
We will demonstrate a procedure for the optimal design of a TWT using the power margin on a communications link as the figure of merit. It is shown that the optimization procedure can be used not only for setting the operating point of the TWT but also for optimization of the physical design of the TWT itself. The use of TWTs designed by such a procedure can in principle yield a substantial improvement in the system link margin over systems employing TWTs designed according to more traditional analog distortion specifications.
