Multi-Conductor Filters

Interdigital, Hairpin, and Combline filters are available. Interdigital and Hairpin filters may be calculated with and without tapped and hairpin resonator end-couplings, and with and without ground end couplers. Combline filters are available with and without tapped end-couplings. The grounded end couplers generally produce more practical geometry than without, but are more costly. Tapped and hairpin coupled ends frequently eliminate impractically small outer gap geometries.
