| Zusammenfassung: | The present invention provides multi-resonator cavity filters in which one or more patch elements are introduced into the coupling apertures between resonators, reducing the strength of the electric field in the aperture gap while maintaining the coupling strength from resonator to resonator. This reduced field strength reduces the sensitivity of the resonators to gap-thickness variations, and allows use of the filter in high-power applications. |
