Abstract: A first dielectric resonator component is joined to a second dielectric resonator component by bonding a first face of the first dielectric resonator component to a second face of the second dielectric resonator component. The first face has a first coupling aperture formed by removing a portion of a coating of first conductive material from the first dielectric resonator component, and the second face has a second coupling aperture formed by removing a portion of a coating of second conductive material from the second dielectric resonator component. The first coupling aperture and said second coupling aperture are aligned with one another when said first face is bonded to the second face. The first dielectric resonator component, which is slab-shaped, and the second dielectric resonator component, which is generally cubed-shaped, form a linear stack having two end faces and four side faces. A first hole is provided at a point along a center line of a side face of the first dielectric resonator component in the direction of orientation of the linear stack, and a second hole is provided substantially in the center of a side face of the second dielectric resonator component to tune a resonant frequency of the pair of joined dielectric resonator components.

Abstract: A radio-frequency filter with at least one dielectric multi-mode resonator is provided. The resonator includes a metal housing with a top surface, a bottom surface, four sectors between the top and bottom surfaces, and including a resonator cavity therein. The resonator further includes a dielectric body positioned inside the cavity, the dielectric body having a first thickness between the top and bottom surfaces of the cavity, wherein there is a gap between the sectors of the housing and the dielectric body, the dielectric body including a hollow on the surface facing the top surface of the housing and on the surface facing the bottom surface of the housing, the dielectric body thus having a second thickness at the location of the hollows, the second thickness being smaller than the first thickness.
