✦ Synopsis

This paper presents a systematic approach for computer aided design of waveguide E-plane diplexers. The approach is based on the principle of equireflection three-ports and using the common junction as the constituent elements of the K-inverters of each channel filter. The method divides an E-plane diplexer in a number of key essential building blocks and adopts the best method for the analysis and synthesis of each key block. This has led to a very accurate and efficient design procedure with minimum computation effort. The advantage of the proposed design procedure has been demonstrated by the implementation of several E-plane bifurcated and T-junction millimeter-wave diplexers. The design algorithms presented in this work can be implemented on a low end Pentium machine. An exact design of a diplexer requires no more than 10 min.
