Center conductor assembly beneficial to batch consistency

Technical Field

The utility model relates to the field of microwave ferrite devices, in particular to a central conductor assembly beneficial to batch consistency.

Background

With the rapid development of the communication field, the circulator/isolator is widely applied to 5G mobile communication, and is mainly used in a base station radio frequency circuit of a communication system to play a role in one-way transmission and receiving and transmitting duplex. As circulators/isolators are developed toward miniaturization, higher demands are placed on the mass production manufacturing process.

The center conductor assembly is one of the core components of the circulator/isolator. Currently, the assembly method of the center conductor assembly is: placing ferrite in the center of the central conductor, and adhering PI films on branches of the central conductor; and bending the branch of the integrated central conductor bonded with the PI film along the outer side wall of the ferrite used for manufacturing the patch type circulator, so that the projection of the center of circle of the PI film in the vertical direction is overlapped with the projection of the center of circle of the ferrite in the vertical direction, and obtaining the central conductor assembly.

In the assembling process, because the bending lines of the branches of the central conductor are random when the central conductor is bent, the complete overlapping of the projection of the center of the PI film in the vertical direction and the projection of the center of the ferrite in the vertical direction cannot be ensured, so that the obtained central conductor assembly is inconsistent, and the batch consistency of one of the device indexes is poor.
