Description

Technical Field

[0001] The utility model relates to the technical field of filters, specifically a cavity structure for a 5G network communication filter. Background Art

[0002] With the development of communication technology, 5G networks are becoming more and more popular. In 5G network communication projects, filters are very necessary equipment. Filters are electronic components that allow specific frequency components in the signal to pass through and greatly attenuate other frequency components. They are used to solve interference problems between wireless communication systems of different frequencies and forms. Filters are the components with the highest value in the RF front end of smartphones. According to different materials, filters can be divided into metal cavity filters and ceramic dielectric filters. Among them, ceramic dielectric filters have the advantages of small size, light weight and high Q value. With a mature industrial chain and cost-effective advantages, they may become the mainstream solution for 5G filters.

[0003] However, existing filters generate a large amount of heat energy during use. If the heat energy is not discharged in time, the filter may overheat, which may cause the filter performance to decline or be damaged. Therefore, improvements are needed. Utility Model Content
