Microwave vertical interconnect through circuit with compressible conductor

摘要

The microwave transmission line, comprises an electrically conductive trough member, which defines a trough. A dielectric filler element is disposed within the trough, and has formed in it an opening extending between two ends. A centre conductor is disposed within the opening, and has a first compressible conductor member formed of thin metal wire densely packed within the opening. The compressible conductor member has a first end protruding from the opening at the first trough end by a contact dimension to form a first compressible contact and a rigid conductor member disposed within the opening to define a dielectric-filled trough transmission line portion. The rigid conductor member has a first end in a compression fit with the first end of the compressible element. The trough is characterised by a square cross-sectional configuration. The trough is a U-shaped trough. The centre conductor is defined by the compressible member, which extends through the opening from the first trough end to the second trough end. The compressible member protrudes from the second trough end to define a second compressible contact.
