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.

Abstract: An apparatus includes a measurement structure for performing measurements of an RF device. The measurement structure includes an aperture in a conductive surface of the RF device and a conductive projecting region projecting into the aperture from a conductive perimeter of the aperture and electrically connected to that conductive perimeter. The aperture has a similar width in all dimensions. A combined shape of the aperture and the conductive projecting region does not possess even rotational symmetry about a point where a signal conductor will be placed on the conductive projecting region in order to conduct RF energy between the measurement structure and an external measurement instrument for performing the measurements. The measurement structure may be used for performing measurements of a multimode resonator, the measurements comprising one or more of resonant frequencies and quality factors of resonant modes of the resonator.
