AI Technical Summary

Technical Problem

In traditional combiners, the bridge and filter components are arranged on the same side, resulting in insufficient space utilization, a large overall size of the combiner, complex signal transmission paths, and high losses, making it difficult to meet the requirements of miniaturization and high integration.

Method used

The bridge assembly is arranged along the length of the housing, and the filter assembly and bridge assembly are placed on different sides of the housing. The signal transmission path is optimized by vertical coupling and parallel arrangement, reducing additional connection structures and long-distance wiring.

Benefits of technology

It reduces the space occupied by the combiner in the wide side direction, improves space utilization, reduces the complexity and loss of the signal transmission path, and enhances the quality of the combined signal and the integration of the equipment.

Abstract

This disclosure provides a combiner with a biased bridge structure, comprising a housing, a bridge assembly, a connector assembly, and two filter assemblies. The housing has a bridge receiving cavity, a combining signal cavity, and a filter signal cavity. The bridge assembly is arranged along the length of the housing on the side facing away from the connector assembly and includes an orthogonal bridge sub-assembly and a combining flybar sub-assembly. The orthogonal bridge sub-assembly is located in the bridge receiving cavity and connects the filter assembly and the combining flybar assembly. The combining flybar assembly is located in the combining signal cavity and connects to the output end of the connector assembly. This structure, by arranging the bridge assembly along the length direction, compresses the space along the wide side, improves space utilization, reduces additional connection structures and signal transmission complexity, and achieves a compact design suitable for integration into miniaturized devices. Simultaneously, it shortens the transmission path between the filter assembly and the bridge assembly, reduces signal loss caused by long-distance wiring and connectors, and effectively improves the quality of the combined signal.
