<p>A multi-mode cavity filter, including first and second dielectric resonator bodies, each incorporating a piece of dielectric material, a first piece shaped to support a first resonant mode and a second resonant mode that is substantially degenerate with the first mode, and the second piece shaped to support a third resonant mode and a fourth resonant mode that is substantially degenerate with the third mode, a layer of electrically conductive material in contact with and covering a surface of the first and a surface of the second dielectric resonator bodies, an aperture in the layer, wherein the aperture includes first and second portions, wherein the first portion transfers signals from the first or second resonant mode to the third or fourth resonant mode and the second portion transfers signals from the first or second resonant mode to the third or fourth resonant mode in parallel.</p> |
