The patent of the present invention discloses a special-shaped cavity multi-mode resonance structure and a filter containing the resonance structure, including a cavity and a cover plate, a dielectric resonance block and a dielectric support frame are arranged in the cavity, and at least one end face of the cavity is Concave or convex, at least one end face of the dielectric resonant block is convex or concave, the dielectric resonant block and the dielectric support frame form a three-mode dielectric resonator rod, one end or any end of the dielectric resonant block similar to a cube is connected to the dielectric support frame respectively, the dielectric The support frame is connected with the inner wall of the cavity, and the dielectric resonance block forms three-mode resonance in the three directions of the X, Y, and Z axes of the cavity. The use of the cavity filter of the present invention can ensure that a high Q value can be obtained with a small distance between the resonant rod and the cavity, and at the same time, the tuning range of the tuning screw is increased, and the small distance between the cavity and the dielectric resonant block is reduced. The sensitivity of the resonance frequency is convenient for production debugging and reduces the production cost.
Description
technical field [0001] The invention relates to base station filters, antenna feeder filters, combiners and anti-interference filters used in the field of wireless communication. The types of filters can be band-pass, band-stop, high-pass and low-pass. A special-shaped cavity three-mode resonant structure and a filter containing the special-shaped cavity three-mode resonant structure. Background technique [0002] With the rapid development of the fourth-generation mobile communication to the fifth-generation mobile communication, the requirements for miniaturization and high performance of communication equipment are getting higher and higher. Traditional filters are gradually replaced by single-mode dielectric filters due to their large metal cavity volume and general performance. Single-mode dielectric filters mainly include TE01-mode dielectric filters and TM-mode dielectric filters, TE01-mode dielectric filters and The TM mode dielectric filter generally adopts a singl...
