This software package seeks to improve waveguide filter and diplexer design and decrease performance variations without creating overly stringent manufacturing tolerances. The accompanying manual helps the reader to cut design time and improve accuracy by quickly and easily predicting performance parameters before building costly prototypes. Using the mode-matching method as a foundation, the software supplies a full-wave solution for filter discontinuities, aiding you in the design of E-plane waveguide filters specifically intended for microwave and millimeter-wave applications. This means you can substantially reduce development and production costs, reduce time-to-market, and effectively increase circuit performance.
