Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the connection between the existing electric bridge and the winding load with joints will cause an additional insertion loss of 0.2dB, and increase the cost by about 40 yuan. The components that affect the intermodulation index are Joint butt tightness

Embodiment Construction

[0020] In order to further understand the content, features and effects of the present invention, the following examples are given, and detailed descriptions are given below with reference to the accompanying drawings.

[0021] The production method of the direct connection between the wire winding load and the inner conductor of the electric bridge provided by the present invention, the intermodulation of the RG402 wire winding load can reach -155dBc, and the RG402 wire winding method is used as the load to dissipate the output power of one of the bridges. The interface between the low intermodulation load and the bridge is generally connected with a connector, which will cause insertion loss and increase the cost. The invention designs the interface joint between the RG402 wire and the electric bridge, referred to as "402-JFD (welding wire joint)", one end of which is welded to the RG402 wire, and the other end is directly welded to the inner conductor of the electric bridge ...

Abstract

The invention belongs to the mobile communication field and discloses a method and system for directly connecting a winding load and a bridge inner conductor. One end of a bonding wire connector is welded with an inner conductor bonding wire, and the other end of the bonding wire connector is in seamless connection with the bridge inner conductor through an inner conductor connection pin; a four-hole fixing clamp is evenly arranged at the outer periphery of the bonding wire connector; and the four-hole fixing clamp is fixed onto a bridge fixing device through a screw. According to the method and system of the invention, the 402-JFD bonding wire connector is designed; one end of the 402-JFD bonding wire connector is welded with the 402-JFD wire, and the other end of the 402-JFD bonding wireconnector is in seamless connection with the bridge inner conductor, and therefore, the insertion loss of original connector butt-joint can be decreased by 0.2dB or more; the cost of the designed connector is reduced by more than 40 yuan compared with that of two butt-joint DIN connectors, and the seamless connection of the integrated connector and the bridge inner conductor ensures more stable inter-modulation; costs can be saved; loss can be reduced; and product inter-modulation stability can be increased.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and a system for directly connecting a wire-wound load to an inner conductor of an electric bridge. Background technique [0002] At present, mobile communication carrier expansion commonly uses two rack equipment for co-frequency combination, Telecom L800 and CDMA co-frequency combination, Unicom GSM900 and LTE900 co-frequency combination, etc. Insert the original antenna port to solve the problem of not needing to add new antennas. The co-frequency combining unit is connected to the nearest base station, which requires high intermodulation indicators (2*43dBm@-155dBc), so the product price is high. Domestic passive device manufacturers usually use winding wires as dissipative loads to solve intermodulation problems. The same-frequency combining unit (two inputs and one output) is generally composed of a high-performance electric bridge + a wire-wound load, where t...
