Title: FILTER AND COMMUNICATION DEVICE
Abstract:
Disclosed are a filter and a communication device. The filter comprises: a filter cavity, a cover plate, a tuning screw, a resonator and a dielectric disc, wherein the cover plate covers the filter cavity, thus forming a resonant cavity, the resonator and the dielectric disc are arranged in the resonant cavity, the resonator and the filter cavity are fixed opposite each other, the tuning screw is arranged on the cover plate in a penetrating manner, the dielectric disc is fixed on one of the tuning screw and the resonator and is spaced apart from the other one of the tuning screw and the resonator, and the spacing distance between the dielectric disc and the other one of the tuning screw and the resonator is adjusted by means of the tuning screw. By the above-mentioned means, the present invention provides a filter and a communication device, which can change a capacitance in a wide range so as to achieve the purpose of adjusting parameters of the filter, thereby correspondingly reducing the required accuracy of manufacturing and assembling of parts, improving the finished filter product yield and increasing the possibility of more powerful filters, and also to achieve a miniaturization design of the filter.
