Four-input and four-output electric bridge

Abstract

The invention relates to a four-input and four-output electric bridge. The analysis and the distribution of the electric bridge on power signals are ensured through adopting novel coupling sheets and novel supporting structures (a long supporting medium and a short supporting medium), a space control medium is arranged between the two kinds of coupling sheets (upper and lower coupling sheets), the four coupling sheets (upper and lower coupling sheets) are tightly locked through plastic screws, the coupling sheets are placed in a cavity of the electric bridge through two kinds of support media (long and short support media), the coupling sheets are connected with a connector through silver plating screws, an inner cover plate and an outer cover plate are installed, and the electric indexes of the electric bridge can be realized. The four-input and four-output electric bridge has the advantages that the structure is simple, the electric indexes can be ensured only through installation, and the further debugging is not needed. Through the replacement via an N type connector, higher compatibility and reliability are realized.

Description

technical field [0001] The invention belongs to the field of mobile communication equipment, and in particular relates to a four-input and four-out bridge; the invention completes signal synthesis and distribution through built-in coupling plates, and specifically controls the thickness of the medium through the distance between the coupling plates to ensure The spacing between the coupling plates is used to realize the synthesis and distribution of the signal of the bridge. Background technique [0002] The broadband bridge is a signal splitting and combining device for wireless communication equipment. The four-input and four-outlet bridge can realize signals in four frequency bands, and complete the communication with the minimum loss, the best matching performance, and the best isolation index. networking. [0003] With the rapid development of communication, 3G standard WCDMA, CDMA2000, TD-SCDMA third-generation mobile communication systems have been constructe...

AI Technical Summary

Problems solved by technology

[0011] First of all, since the four two-input and two-outlet bridges and the four-input and four-outlet system need to be connected by radio frequency cables, the insertion loss of the system is increased, and the allocation index on the broadband cannot be met. Wave influence, resulting in poor standing wave index and isolation index of the system

Secondly, because it is a system, it needs to ensure the indicators, so it is difficult to debug; moreover, the reliability is poor, and the cables and connectors are easy to break and have poor contact after repeated bending and twisting, which will affect the intermodulation indicators; more importantly, The cost is high, four electric bridges and four cables are required, in addition, four ordinary electric bridges are connected, and there is a cable connection in the middle, which takes up a lot of space, is too large, and is inconvenient to use
