Filter & Coupler Design

Microwave and millimeter-wave filters are key components in modern communication systems. SEMCAD X is a powerful tool for the accurate analysis and design of a wide range of filters including high-Q filters.

Key Features

• Extensive CAD import interfacing (.sat, .stl, .dxf, .dws, .iges, .3ds, .step, ProEngineer, etc.) enabling implementation ofcoupling/tuning screws and any geometrical changes due to fabrication
• Inclusion of higher order mode interactions
• Accurate calculation of coupling coefficients between resonators
• Multi-port S-parameter extraction
