Title:
DUAL MODE RESONATOR, FILTER, AND RADIOFREQUENCY UNIT
Document Type and Number:
WIPO Patent Application WO/2019/179524
Kind Code:
A1
Abstract:
Provided in embodiments of the present application are a dual mode resonator, a filter, and a radiofrequency unit. The dual mode resonator comprises: a cavity and a dual mode medium body coupled to the inner surface of the cavity. The dual mode medium body comprises a center part and four parts extending from the center part. The four parts correspond two-to-two to each other and are provided as a cross. A first coupling groove and a second coupling groove are provided on the center part. The direction in which the first coupling groove extends falls between two adjacent parts. The direction in which the second coupling groove extends falls between the other two adjacent parts. The width and/or depth of the first coupling groove and that of the second coupling groove are not equal. Moreover, a preset angle is provided between the direction in which the first coupling groove extends and the direction in which the second coupling groove extends. The first coupling groove and the second coupling groove provide an increased coupling coefficient between two resonant modes of the dual mode resonator. The width and/or depth of the first coupling groove and that of the second coupling groove are not equal, thus implementing discrete control of the positive-negative coupling and of the coupling strength of the dual mode resonator.
