Abstract

The invention relates to a filter. The filter comprises a shell, a cover plate, a resonator and a connecting piece. The shell is provided with an opening. The cover plate covers the opening of the shell. The resonator is arranged in the shell and connected with the cover plate. One end of the connecting piece is connected with the resonator, and the other end is connected with one end, way from the opening, of the shell. The connecting piece is in a telescopic structure. According to the invention, the size error of the filter caused by thermal expansion and cold contraction can be reduced, and good contact of the resonator can be ensured.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a filter. Background technique [0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency or eliminate a power signal of a specific frequency. With the development of wireless communication technology, the application of filters is becoming more and more extensive. However, when the current filter is at high and low temperature, due to thermal expansion and contraction, there will be dimensional errors, which will affect the poor contact of the filter, thereby affecting the performance of the filter. Contents of the invention [0003] The invention provides a filter, which is used to solve the technical problem of poor contact of the...
