Abstract

The invention discloses a micro-wave low-band TM010 mode high-selectivity cavity dielectric filter, which is at least provided with two cylindrical cavity resonators, wherein cylindrical micro-wave dielectric materials are arranged in the cavity resonators and are provided with resonant frequency regulation holes, the cylindrical cavity resonators are numbered according to the sequence, a centralized coupling window is arranged between the two cavity resonators with adjacent serial numbers, resonant frequency adjustment screws and an inter-cavity coupling strength adjustment screw extend into the resonant frequency regulation holes of the cylindrical micro-wave dielectric materials of the cavity resonators and the centralized coupling window respectively, the micro-wave dielectric materials in the head and tail cavity resonators are also provided with probe holes, and probes of input / output interfaces are inserted into the corresponding probe holes respectively. The resonance mode of the metal cylindrical resonators of the filter is a TM010 mode, the electromagnetic field has a simple structure as well as axially symmetrical and even distribution, and the filter has high quality factor, small loss, large power capacity, and small volume, thereby satisfying the need of the development of communication products toward miniaturized and high integration directions.

Description

technical field [0001] The invention relates to a microwave low-band TM 010 High-mode selectivity cavity dielectric filter is suitable for filtering devices for radio frequency signal transmission in the field of radio communication. Background technique [0002] In various modern wireless communication devices, filters, as a commonly used, necessary and widely used component, play an increasingly important role in wireless information transmission technology. At present, microwave filters used in various wireless communication frequency bands are generally realized by coaxial transmission. It is usually composed of a resonant cavity, an inner conductor and corresponding tuning screws, etc., while performance indicators require low loss and high power. , the volume of the resonant cavity will increase correspondingly, which will not only consume a large amount of raw materials, but also put forward higher requirements for its production and processing technology. Cost requ...
