Broadband four-in four-out bridge

The application relates to a broadband four-in four-out bridge comprising a cavity body, an upper cover plate, a lower cover plate, a first bridge, a second bridge, a third bridge, a fourth bridge, a first connector, a second connector, a third connector, a fourth connector, a fifth connector, a sixth connector, a seventh connector and an eighth connector. The broadband four-in four-out bridge has a simple structure, electrical indicators can be ensured once the bridge is installed, and no further debugging is needed. The bridge enables DIN connector replacement to be realized, and thus has extremely high compatibility and reliability. The broadband four-in four-out bridge has the characteristics of small size, convenient installation and use, and good product performance. The broadband four-in four-out bridge has more optimal performance, better distribution performance and better inter-modulation performance.
