An efficient optimization design of a manifold multiplexer using an accurate equivalent circuit model of coupling irises of channel filters

In this paper, an efficient optimization design method for a manifold multiplexer is proposed. For an efficient optimization, equivalent circuit models for coupling irises of channel filters are presented. Equivalent circuit models are obtained from the results of electromagnetic field (EM) analysis. To validate the presented optimization design method, a manifold multiplexer for Ka-band satellite applications is designed and realized. The good agreement between theoretical result and measured one is shown.
