RESONATOR APPARATUS, FILTER APPARATUS AS WELL AS RADIO FREQUENCY AND MICROWAVE DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/259028

Kind Code:

A1

Abstract:

A resonator apparatus, a filter apparatus as well as a radio frequency and microwave device are disclosed. According to an embodiment, the resonator apparatus comprises an electrically conductive case and a dual-mode dielectric resonator provided in the electrically conductive case. The dual-mode dielectric resonator comprises a first dielectric block having a shape of a columnar body whose cross section is a cruciform. A mode coupling structure for coupling two resonant modes of the dual-mode dielectric resonator is provided in the columnar body. A bottom face of the columnar body is supported by an inner face of the electrically conductive case or by a supporting member provided on the inner face of the electrically conductive case. In at least one extending direction of a first extending direction and a second extending direction of the cruciform which are perpendicular to each other, lateral end faces of the columnar body are spaced apart from inner faces of the electrically conductive case.
