Abstract A H-plane waveguide duplexer is analysized with a multi-mode microwave network method in this paper. This method is carried out through three steps: dividing the microwave device to be analyzed into a group of unit components at first, then numerically solving, the electromagnetic boundary-value problems of components one by one to yield their multi-mode network scattering parameters, finally re-combining all the unit components to obtain the total scattering parameters of the original devices to be analyzed.
