An s-parameter adjustable radio frequency connector

Abstract

The present invention provides an S-parameter adjustable radio frequency connector, which includes an outer conductor, wherein the shaft is provided with a cavity, and an open window is provided on the outer wall thereof. The inner conductor is inserted into the cavity of the outer conductor, and is butted with the coaxial cable at the open window, and a certain amount of solder is used to weld the coaxial cable and the coaxial cable. the inner conductor to adjust the S-parameter of the radio frequency connector. The radio frequency connector of the present invention can be welded more stably, so that the welding effect is better, and the actual amount of the solder can be better controlled. Moreover, after the coaxial cable is connected with the RF connector, it is directly connected to the antenna input port, which not only eliminates the main feeder connector, but also maintains the adjustable S parameter of the main feeder; it eliminates the main feeder connector and saves material costs. At the same time as the assembler, three solder joints are reduced at the main feed end with the largest current density, which greatly improves the level of antenna intermodulation.

Description

technical field [0001] The invention relates to the field of radio frequency connectors, and more particularly, to a radio frequency connector with adjustable S-parameters. Background technique [0002] For existing RF connectors, such as 7 / 16Din and 4.3-10 RF connectors in the field of base station antennas, the outer conductor of the connector completely wraps the inner conductor of the connector. After the connector is made, the connector is a closed part, and S-parameters cannot be debugged. At the same time, in the actual production of the antenna, the connection between the RF connector and the antenna input port of the base station is usually connected by a connector with S-parameter debugging function, and this connector can cooperate with the S-parameter. Specifically, the connector introduces three additional solder joints at the main feed end with the largest current density. However, the increase of solder joints at the main feed end greatly increases the probab...

Problems solved by technology

[0003] The present invention aims to overcome the defects of the above-mentioned prior art that the S parameters cannot be debugged and the antenna intermodulation index has a high probability of deterioration, and provides a radio frequency connector with adjustable S parameters, which is used to realize that the S parameters of the radio frequency connector can be debugged, Realize the direct connection between the RF connector and the antenna input port through the cable, thereby eliminating the need for additional connectors at the main feeder end, reducing 3 additional solder joints at the main feeder end with the highest current density, and improving the antenna intermodulation index
