Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a modular structure filter. Background Art

[0002] In the 5G era, with the upgrade of operator systems and the integration of filters of different frequencies, in addition to the improvement and tightening of filter performance indicators, higher requirements are also placed on the structural stability of filters and the manufacturing costs of filters. The current cost is a strong competitive advantage of the entire filter.

[0003] In order to reduce the investment cost of network construction, operators have begun to share base stations and filter designs to be compatible with different frequency bands. In addition, operators and equipment manufacturers have begun to platformize antennas and filters, and provide fixed dimensions, port positions and engineering installation methods to filter manufacturers for filter internal structure and performance design. Different application scenarios correspond to different performance indicators. Since the product dimensions, port positions and engineering installation methods are consistent, and the existing filters are integrated structures, the entire appearance and engineering installation methods need to be redeveloped and produced along with the filters due to changes in performance indicators and internal structures, resulting in higher R&D and manufacturing costs.

[0004] Therefore, a modular structure filter is urgently needed to solve the above problems. Utility Model Content
