Abstract
A pair of joined dielectric resonator components of an RF filter includes a first dielectric resonator component and a second dielectric resonator component. The first dielectric resonator component includes a first block of dielectric material, which has a coating of a first conductive material and at least one planar face. The at least one planar face includes a first aperture formed by removing the coating of first conductive material from a portion of the planar face of the first block. The second dielectric resonator component includes a second block of dielectric material, which has a coating of a second conductive material and at least one planar face. The at least one planar face includes a second aperture formed by removing the coating of second conductive material from a portion of the planar face of the second block. The first and second dielectric resonator components are joined to one another with the coating of first conductive material on the planar face of the first block in contact with the coating of second conductive material on the planar face of the second block, and with the first aperture aligned with the second aperture. The second dielectric resonator component has a hole through the coating of second conductive material and into the second block of dielectric material. The hole is outside of the second aperture, and controls electric-field coupling between the first and second dielectric resonator components.
