Ka-Band Multiplexer With Multiple Input and Output Ports

Abstract

Aiming at the development of Ka-band HTS satellite and the application of microwave technology, a new type of Ka-band OMUX with three input ports and five output ports is presented. The whole design process is combined with network model synthesis, field path equivalent hybrid model, pattern matching method and EM tools. The design procedures are included in this paper. The optimized dimensions and the simulated results are presented. Due to the use of hybrid equivalent circuit model of sleeveless multiplexer, unnecessary full-wave EM simulation is avoided, design efficiency is greatly accelerated, and simulation performance of OMUX is guaranteed to meet design indexes.
