Abstract

Disclosed is a cavity filter capable of easily fixing a tuning bolt while minimizing external protrusion of the tuning bolt. The cavity filter including a tuning bolt comprises: a housing which is opened upwards and includes a plurality of cavities opened upwards therein; a cover sealing the housing; nuts which have first screw threads and formed on the cover; and tuning bolts which are coupled tothe nuts. Each tuning bolt includes: a first nut coupling unit including second screw threads coupled to the nut; and a second nut coupling unit including third screw threads coupled to the nut and aplurality slits whose one ends are opened. The length from the center of the tuning bolt to the third screw threads is longer than the length from the center of the tuning bolt to the second screw threads.

Description

technical field [0001] The present invention relates to a cavity filter with tuning bolts, and more particularly, to a cavity filter that minimizes the outward protrusion of the tuning bolts and can easily fix the tuning bolts. Background technique [0002] A cavity filter is a filter that passes only frequencies in a desired frequency band among various input frequency components and attenuates the remaining frequencies, and many types and forms have been developed. [0003] The bandpass frequency of the cavity filter is determined by the inherent inductance and capacitance components of the corresponding filter. [0004] In addition, in order to perform tuning of the cavity filter in order to adjust the frequency band passed by the cavity filter as required, the tuning of the cavity filter includes a process of moving the tuning bolt in the up-down direction. [0005] figure 1 It is a figure which shows the cavity filter provided with the normal tuning screw. [0006] r...
