S-parameter adjustable radio frequency connector

Abstract

The invention provides an S-parameter adjustable radio frequency connector which comprises an outer conductor, a cavity is arranged on a middle shaft of the outer conductor, an open window is arrangedon the outer wall of the outer conductor, and the open window is formed by exposing the cavity of the outer conductor after a part of the outer wall of the outer conductor is cut off; and the connector also comprises an inner conductor which is inserted into the cavity of the outer conductor and is in butt joint with a coaxial cable at the open window, wherein a certain amount of solder is adopted to weld the coaxial cable and the inner conductor so as to adjust the S parameter of the radio frequency connector. According to the radio frequency connector, welding can be carried out more stably, so that the welding effect is better, and the actual use amount of the solder is better controlled. Moreover, the coaxial cable is directly connected with an antenna input port after being connectedwith the radio frequency connector, so that a main feed end connecting piece is omitted, and the S parameter of a main feed end is kept adjustable; while the main feed end connecting piece is omittedand the material cost and the assembly are saved, three welding spots are reduced at the main feed end with the maximum current density, so that the intermodulation level of the antenna is greatly improved.

Description

technical field [0001] The present invention relates to the field of radio frequency connectors, more specifically, 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 manufactured, the connector is a closed part, and the S parameters cannot be debugged. At the same time, in the actual production of the antenna, the RF connector and the antenna input port of the base station are usually connected through a connector with an 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 highest current density. However, the increase of the solder joints at the main feed end greatly increases the ...
