Power Splitter/Combiner

Abstract

The present disclosure relates to a power divider / combiner. The power divider / combiner includes: a common port, multiple branch ports, branches corresponding to the multiple branch ports, at least one phase compensation device set in the power divider / combiner according to the preset connection relationship, and at least one isolation resistor. By setting at least one phase compensation device in the power divider / combiner, not only the port isolation and insertion loss performance of the power divider / combiner can be improved, but also the radiation coupling between the split ports can be offset to further improve the port performance. isolation. In addition, the phase imbalance caused by various types of interference can be easily and conveniently compensated by the phase compensation device, which greatly reduces the number of debugging and board casting, and shortens the development cycle. Moreover, the power divider / combiner is applicable to different installation environments, and can ensure high isolation, which is convenient for development and production, and is more conducive to mass production and popularization and application.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular to a power divider / combiner. Background technique [0002] A power divider is a radio frequency device that divides one radio frequency signal into two or more channels, equally or unequally divided, and it can also synthesize multiple radio frequency signals into one signal, which can be called a power combiner at this time. It is widely used in signal distribution and signal combining applications, such as multi-antenna systems, multi-base station systems, multi-channel signal systems, and home cable TV distribution networks. Indexes such as port isolation, insertion loss, and phase balance have an important impact on the performance of the entire power divider. [0003] The current power divider is designed due to size defects, radiation coupling, and phase imbalance introduced by surrounding media and metal interference, resulting in a decrease in port isolat...

AI Technical Summary

Problems solved by technology

[0003] The current power divider is designed due to size defects, radiation coupling, and phase imbalance introduced by surrounding media and metal interference, resulting in a decrease in port isolation (generally 20DB~25DB), requiring repeated debugging and boarding, and a long development cycle.

Moreover, after the design and commissioning of the current power divider are completed, changes in the installation position and shielding structure may cause phase imbalance, resulting in a decrease in port isolation

Therefore, it is necessary to design different power splitters for different installation environments, which makes the development, production and management of power splitters more cumbersome
