Large Scale Minimax Optimization of Microwave Multiplexers

Abstract

A new technique for contiguous-band multiplexer design involving an arbitrarily large number of channels and design parameters is described. The technique, based on network decomposition and sensitivity measures of practical microwave multiplexer structures, employs a sequence of relatively small optimization problems which correspond to growing a multiplexer by adding one or more channels at a time to the structure. The approach is illustrated by a 16-channel, 12 GHz multiplexer design involving 240 nonlinear design variables.
