Description

Technical Field

[0001] The utility model relates to the technical field of filters, and specifically to a 5G filter cavity structure with enhanced heat dissipation. Background Art

[0002] As a typical frequency selection device, the filter can effectively suppress useless signals and play the role of selecting signals, attenuating noise and filtering interference. With the promotion of green energy and the increasingly strong demand for cost reduction, the demand for low-cost filters is increasing. At the same time, with the advent of the 5G era, 5G filters have emerged. With the rapid development of mobile communications, miniaturization and lightweight have also become the future development trend of microwave RF devices. Due to the precise requirements for frequency selection and the high temperature of the filter itself, it is often necessary to ensure that the temperature inside the filter is not too high during work. Therefore, in some RF working units, filters with heat dissipation structures are often used.
