摘要： Embodiments of this application provide a dielectric filter, a duplexer, and a communications device, relate to communications device components, and intend to resolve problems of a great difficulty in matching between different filters and high layout space consumption that are caused by addition of a low-pass filter cascaded with the dielectric filter. The dielectric filter includes a dielectric body, and a wideband filtering structure and a narrowband filtering structure that are disposed in the dielectric body. The wideband filtering structure includes a groove and at least one first resonator. The groove is disposed on a first surface of the dielectric body and is configured to adjust a frequency position of a passband of the wideband filtering structure. The first resonator includes a through hole and an open loop. The through hole penetrates the bottom of the groove and a second surface of the dielectric body. The open loop is located on a bottom surface of the groove and is disposed around an opening of the through hole. The narrowband filtering structure includes at least one second resonator, and the second resonator includes a blind hole disposed on the second surface of the dielectric body. The first surface and the second surface of the dielectric body are disposed oppositely.

摘要： Embodiments of this application provide a dual-mode resonator, a filter, and a radio frequency unit. The dual-mode resonator includes: a cavity and a dual-mode dielectric body coupled to an inner surface of the cavity, where the dual-mode dielectric body includes a central part and four components that protrude from the central part, the four components are disposed opposite to each other in pair and are in a cross shape, and a first coupling groove and a second coupling groove are provided on the central part, where an extension direction of the first coupling groove is between two adjacent components, an extension direction of the second coupling groove is between the other two adjacent components, the widths and/or the depths of the first coupling groove and the second coupling groove are different, and the extension direction of the first coupling groove and the extension direction of the second coupling groove are at a preset angle. Due to the first coupling groove and the second coupling groove, there is a relatively large coupling coefficient between two resonance modes of the dual-mode resonator. The widths and/or the depths of the first coupling groove and the second coupling groove are different. Therefore, independent control over positive and negative coupling and coupling strength of the dual-mode resonator is implemented.
