Abstract:An equivalent circuit theory design of a class of rectangular waveguide E-plane T-junction diplexer with E-plane all-metal insert filters is presented. Element values of equivalent circuit models of E-plane T-junction proposed in 1] are computed and approximated. The parameters of the filters designed by 2] are also given. By use of the network combining technique, the scattering matrix of the diplexer is obtained and optimized according to the diplexer specification with a novel objective function. The experimental results show a fairly good agreement with the computed results.
