Abstract

The invention discloses a filter and communication equipment. The filter comprises a cavity and a filtering branch, wherein the filtering branch is arranged in the cavity and composed of twelve low-pass pieces, the first low-pass piece to the eleventh low-pass piece of the filtering branch are sequentially coupled, and the twelfth low-pass piece of the filtering branch is arranged between the tenth low-pass piece of the filtering branch and an output port of the filter, so that a cross coupling zero point is formed; and the working frequency band of the filtering branch is 300 to 960 MHz. By means of the mode, the filter is small in size, light in weight and high in anti-interference performance.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a filter and a communication device. Background technique [0002] Microwave filters are the key equipment of modern mobile communication systems, and are widely used in wireless communication base stations and various communication terminals; microwave cavity filter structures are composed of radio frequency connectors, cavity bodies, cover plates, multiple resonator units, and Composed of frequency tuning and coupling strength adjustment components, the resonant frequencies of multiple resonant units are distributed within the passband range, and have a blocking function for signals outside the resonant frequency, thereby realizing the selection function of microwave transmission signals; the cavity filter has a reliable structure , Filter frequency bandwidth, parasitic passband away from the channel, high Q value, stable electrical performance, good heat dissip...
