摘要： The present invention provides a resonator, including: a resonant cavity casing, a cover that covers an open end of the resonant cavity casing and is connected to the resonant cavity casing, a resonance tube located inside a resonant cavity, and a tuning screw, where the tuning screw is connected to the cover and stretches into space encircled by the resonance tube, the resonator further includes a dielectric material that is filled in the resonant cavity and whose dielectric constant is greater than 1, and the dielectric material is filled in a capacitance area formed between the top of the resonance tube and the cover. The present invention further provides another resonator, where a tuning rod of the resonator is rotatable relative to a dielectric material filled in a resonant cavity, and face-to-face surfaces of the tuning rod and the dielectric material are a non-circular structure, so that the tuning rod can adjust a frequency when being rotated relative to the dielectric material. According to the resonator provided in the present invention, a conductor loss can be reduced, a dielectric loss does not increase greatly, and costs are relatively low. The present invention further provides a filter, a duplexer, and a multiplexer that use the resonator.

摘要： The present invention provides a dielectric filter, including a cavity, a resonant cavity, a cover plate, and a connecting rib. The cavity includes an accommodating cavity and a cavity wall surrounding the accommodating cavity. A resonator is disposed inside the accommodating cavity, the resonator includes a support medium and a main medium, the support medium is disposed on a bottom wall of the accommodating cavity, and the main medium is disposed on the support medium. The cover plate covers the cavity to close the accommodating cavity. The connecting rib is accommodated in the accommodating cavity, and is disposed on a radiation plane formed between a radiation radiated from a center axis of the resonator onto the cavity wall and the center axis of the resonator, where a shortest distance between the connecting rib and the main medium is greater than a preset value. The present invention achieves an object of pushing away a high-order harmonic wave. The present invention further provides a dielectric filter component and a base station.
