Filter input and output structure capable of being directly connected with PCB

Abstract

The invention discloses a filter input and output structure capable of being directly connected with a PCB, and belongs to the technical field of filters. The filter input and output structure capable of being directly connected with the PCB comprises a debugging clamp, the debugging clamp is detachably connected with an isolation plate, the upper side of the isolation plate is provided with a cavity, the upper side of the cavity is provided with a cover plate, an output port resonator is arranged on the inner side of the cavity, ten output port resonators are arranged on the inner side of the cavity, the ten output port resonators are detachably connected to a debugging clamp through output port resonator fixing screws, the lower sides of the output port resonators at the two ends are fixedly connected with input and output microstrip line matching copper sheets, the input and output microstrip line matching copper sheets extend outwards, and the left side of the debugging clamp is provided with an output PCB matching board. According to the invention, the problem that a conventional filter cannot be directly connected with a PCB integrated circuit during input and output is solved, and the product index is easy to control compared with a conventional structure.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a filter input and output structure that can be directly connected to a PCB board. Background technique [0002] A filter is a device for filtering waves. "Wave" is a very broad physical concept. In the field of electronic technology, "wave" is narrowly limited to the process of describing the fluctuation of the value of various physical quantities with time. This process is converted into a time function of voltage or current through the action of various sensors, which is called the time waveform of various physical quantities, or called a signal; [0003] However, in the traditional filter design process, some products have special applications, which need to be soldered on the PCB and the integrated circuit on the PCB to work together. The input and output of the conventional filter are in the form of connectors, which cannot be directly connected due to the fixed input and o...
