Abstract

The embodiment of the present application discloses a filter coupling structure and a processing method for reducing the delivery cost of a filter. In the embodiment of the present application, the filter coupling structure includes at least two resonant cavities. Each resonant cavity is an internal space that is a combination of a resonant cavity wall, a resonant cavity bottom plate, and a resonant cavity cover plate. The at least two resonant cavities are successively connected and each include a resonator. Coupling spacer assembly are arranged between every two of the at least two resonantcavities, wherein each coupling spacer assembly includes a first coupling spacer and a second coupling spacer, the first coupling spacer is connected to the resonance cavity wall and the resonance cavity bottom plate to block the two adjacent resonance cavities, and the second coupling spacer is connected to the resonance cavity bottom plate and intersects the first coupling spacer.

Description

technical field [0001] The present application relates to the mechanical field, in particular to a filter coupling structure and a processing method. Background technique [0002] With the rapid development of wireless communication, the hardware competition of communication equipment is becoming more and more fierce, and cost control is becoming more and more important. The cost of filters in wireless communication is relatively high. The current filter, in the scene of high demand, has usually achieved low-cost delivery of die-casting, and the mold cost is shared through a large number of demands. by figure 1 As shown, the filter includes at least two adjacent cavities 11 of resonators 12, a coupling window 13 is opened on the partition between two adjacent resonant cavities 11, and a shielding cover 14 is assembled on the cavity A cylindrical tuning screw 15, when the cover plate and the cavity are assembled, the tuning screw 15 can move up and down in the middle of th...
