    Abstract: Embodiments of this application provide a dielectric filter and a communications device, and relate to the field of wireless communications device technologies. The dielectric filter includes a dielectric block. At least two resonant through holes that are parallel to each other are provided in the dielectric block. The resonant through hole is a stepped hole. The stepped hole includes a stepped large hole and a stepped small hole that are arranged coaxially and that are in communication. The stepped small hole passes through a first surface of the dielectric block. The stepped large hole passes through a second surface of the dielectric block. A stepped surface is formed between the stepped large hole and the stepped small hole. The surfaces of the dielectric block are covered with conductor layers. The conductor layers cover the surfaces of the dielectric block and inner walls of the stepped large hole and the stepped small hole. A conductor layer of the inner wall of the stepped large hole is short-circuited with a conductor layer of the second surface. A conductor layer of the inner wall of the stepped small hole is short-circuited with a conductor layer of the first surface. A loop gap that does not cover the conductor layers is provided on the stepped surface. The loop gap is arranged around the stepped small hole.

    Abstract: Embodiments of the present invention provide a transverse electromagnetic mode dielectric filter. A near-end rejection structure is disposed inside the filter. By flexibly designing a shape, a location, and a size of the near-end rejection structure, a transmission zero or zero cavity function is implemented, and a radio frequency signal on a high-frequency end or a low-frequency end out of a passband of the filter is rejected, thereby achieving good near-end rejection performance. The embodiments of the present invention further provide a radio frequency module and a base station.

    Abstract: The present invention relates to a waveguide E-plane filter component comprising a first and second main part (2) with a corresponding first and second waveguide section part (3). The main parts (2) are mounted to each other, such that a waveguide arrangement is formed. The waveguide arrangement has a height and a width. The waveguide E-plane filter component further comprises at least one electrically conducting foil (10, 11) that is placed between the main parts (3), said foil comprising a filter part (25) with apertures (12a, 12b, 12c, 12d). Each pair of adjacent apertures is separated by a corresponding foil conductor (13a, 13b, 13c) of which at least one is constituted by a tuning foil conductor (13a) that has a first, second and third part (14, 16, 18) with a corresponding first, second and third width (15, 17, 19).

    Abstract: Embodiments of the present invention provide a TEM mode dielectric filter and a manufacturing method thereof. The mode dielectric filter provided by the present invention includes a dielectric body (1) and a silver plating layer (2), where the silver plating layer covers a surface of the dielectric body, and a dielectric constant of the dielectric body is less than or equal to 21. The TEM dielectric filter provided by the present invention has a large energy storage space in a single resonant cavity of a dielectric material, and has a high quality factor. An insertion loss of the TEM dielectric filter is low, and electrical conductivity of the silver plating layer is high.
