Problems solved by technology

[0003] Traditional filter low-pass components usually have a prefabricated insulating heat-shrinkable sleeve outside the low-impedance transmission line section to achieve insulation from the inner wall of the filter cavity. The insulating heat-shrinkable sleeve The thickness and tightness cannot be controlled, which will affect the stability of low-pass component assembly, which will have a great impact on the intermodulation of the filter

Abstract

The invention relates to a low-pass assembly of a filter. The low-pass assembly comprises an input port, an output port and transmission line segments arranged between the input port and the output port. The transmission line segment comprises a plurality of low-impedance transmission line segments and a plurality of high-impedance transmission line segments, the low-impedance transmission line segments and the high-impedance transmission line segments are sequentially arranged at intervals, an insulating shell is integrally formed outside each low-impedance transmission line segment, and an elastic piece is integrally formed between every two adjacent insulating shells. The assembly stability of the low-pass assembly can be ensured, and the stability of filter intermodulation can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of radio frequency communication, in particular to a filter low-pass component. 【Background technique】 [0002] The low-pass component is a key component of the filter, and its assembly stability has a great influence on the intermodulation of the filter. [0003] Traditional filter low-pass components usually have a prefabricated insulating heat-shrinkable sleeve outside the low-impedance transmission line section to achieve insulation from the inner wall of the filter cavity. The insulating heat-shrinkable sleeve The thickness and tightness cannot be controlled, which will affect the stability of low-pass component assembly, which will have a great impact on the intermodulation of the filter. 【Content of invention】 [0004] The purpose of the present invention is to overcome the disadvantages of the above-mentioned technologies, and provide a filter low-pass assembly, which can ensure the stability of...
