Description

Technical Field

[0001] The utility model relates to the technical field of filters, and more specifically, to a filter with an isolation structure. Background Art

[0002] The filter is the most basic microwave electronic device. It is a filtering circuit composed of capacitors, inductors and resistors. The filter forms mainly include planar microstrip and cavity filters. The filter can effectively filter out a specific frequency point in the power line or frequencies other than the frequency point to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency.

[0003] As the application scope of filters becomes wider and wider, it is also common to use filters outdoors. When existing filters are used outdoors, if they encounter rainy weather, due to their poor waterproof performance, some water can easily penetrate into the shell through the heat dissipation port, resulting in an increase in the hidden danger of erosion and damage to the filter body in the shell, affecting the service life and reliability of the filter. Based on this, the utility model designs a filter with an isolation structure to solve the above problems. Utility Model Content
