摘要： Target mode frequencies are calculated for a defined filter component used as a reference for filter components to be tuned. The defined filter component has resonant mode(s), each having a mode frequency which can be tuned to a corresponding target mode frequency via physical adjustment of parameter(s) of the filter component. A tuning equation is formed by linearly relating, via a slope matrix, changes in the mode frequencies to corresponding physical adjustment in the parameter(s), and by using an inverse of the slope matrix as part of the tuning equation. A tuning procedure is performed for a filter component to be tuned, comprising: determining, using the tuning equation, adjustment information for parameter(s) of the filter component to adjust measured mode frequency(ies) of the filter component toward meeting corresponding target mode frequency(ies) for the resonant mode(s) within corresponding tolerance(s); and outputting the determined adjustment information for physical adjustment of the parameter(s).

摘要： The present invention relates to a multi-mode filter comprising a carrier on which is mounted a dielectric resonator having a covering of an electrically conductive material in which there is provided an aperture and a coupling structure for coupling input signals to the dielectric resonator or for extracting filtered output signals from the dielectric resonator. The carrier is provided with an enclosing formation of electrically conductive material, which enclosing formation is electrically coupled to the electrically conductive covering of the dielectric resonator, such that the covering and the enclosing formation together form an electrically conductive enclosure for the dielectric resonator. The enclosure formed from the covering of the dielectric resonator and the enclosing formation increases the isolation of the filter and reduces leakage. The filter of the present invention is particularly suitable for use in cascaded resonator filter arrangements, and in duplex/diplex filters.

摘要： A multi-mode cavity filter has a resonator body with a face and a conductive covering. The face has an uncovered area through which a signal can be coupled into or out of the body. A boundary exists between the uncovered area and the covering. A first vector drawn between two most distal points on the boundary and not crossing the covering is such that a second vector drawn between two other points on the boundary and orthogonal to the first vector has a length that is at least 70% that of the first vector. The length of the first vector is at least 20% of the length of the shortest vector that passes through a centroid of the face and extends completely across the face.
