Abstract

Bei einem aus mehreren Koaxial-Resonatoren (1, 5; 2, 6; 3, 7; 4, 8) bestehenden Mikrowellenfilter sollen parasitäre Kopplungen möglichst weitgehend reduziert werden, um eine breitbandige symmetrische Filtercharakteristik realisieren zu können. Dazu ist mindestens eine induktive Überkopplung (16) zwischen zwei elektrisch nicht benachbarten Koaxial-Resonatoren (1, 5; 4, 8) vorgesehen, und mindestens eine Hauptkopplung (14, 15) zwischen elektrisch benachbarten Koaxial-Resonatoren (2, 6; 3, 7) in der Umgebung der Überkopplung (16) ist kapazitiv.
