摘要： A cross-coupled filter includes a resonant structure including a plurality of columns of resonant units, each column of resonant units includes at least two resonators. A dominant coupling mode of a coupling between two adjacent resonators in a same column is electrical coupling or magnetic coupling. Dominant coupling modes of a plurality of groups of two adjacent resonators in the same column alternate between electrical coupling and magnetic coupling. A dominant coupling mode of a coupling between two adjacent resonators in adjacent columns is electrical coupling or magnetic coupling. Dominant coupling modes of a plurality of groups of two resonators of two adjacent columns alternate between electrical coupling and magnetic coupling, to form at least a set of cross-coupling. The present disclosure realizes miniaturization and light weight in structural characteristics, and realizes low loss and good harmonic characteristics in electrical performance.

摘要： An apparatus includes a filter. The filter includes a metal structure forming a cavity and includes a ceramic block, which is suspended in the cavity. The ceramic block has two removed portions, the removed portions removed from two opposing sides of the ceramic block. The ceramic block further has one or more slots that that span a region of ceramic between the two removed portions and connects chambers formed by the two regions with chambers formed by the one or more slots, wherein a combined structure of the ceramic block, cavity, and metal structure supports multiple fundamental TM modes and one fundamental TE mode. The filter comprises multiple coupling structures to couple radio frequency signals into and out of the filter. The apparatus may include multi-cavity filters including one and typically multiple ones of the filters.

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 bandpass filter has a combline structure having a plurality of cascaded nodes. A plurality of nodes in the filter are connected both to resonant elements (a.k.a. resonators) and non-resonant elements (including elements having inductances and/or capacitances that do not resonate in a predetermined frequency band of interest). The resonant frequencies of the resonant elements may be adjusted, in order to adjust the location of the center frequency and/or the width of the passband of the filter. The characteristics of the resonant and non-resonant elements are selected such that the poles of the filter, when plotted on the complex plane, move substantially along the imaginary axis when the resonant frequencies are adjusted, without substantial movement along the real axis. The resulting bandpass filter has substantially constant losses and substantially constant absolute selectivity over a relatively wide range of bandwidths.

摘要： The present invention uses TE01(nδ) single-mode resonators in different orientations that are cascaded along an evanescent mode waveguide. By exploiting multiple orthogonal evanescent modes that can alternatively by-pass, or excite the resonators, cross-coupling between non-adjacent resonators is established and properly controlled. Pseudoelliptic filters are realized without using cumbersome cross-coupled architectures, or reduced spurious performance multi-mode resonators. A 6th order filter with two transmission zeros in the lower stopband, a 5th order filter with three transmission zeros, and an 8th order filter with four transmission zeros are included as embodiments of the present invention.
