Abstract
A substrate interface system and method are provided for connecting a coplanar waveguide transmission line to a coaxial connector. The system comprises a substrate having a top surface with a coplanar waveguide having a transmission line interposed between coplanar groundplanes. A housing wall assembly has an aperture and an interior surface adjacent the substrate coplanar waveguide. A coaxial connector, mounted in the housing wall assembly through the aperture, has a center conductor connected to the coplanar waveguide transmission line and a ground connected to the housing wall assembly. Extensions are mounted on the wall assembly interior surface, connected to the coplanar waveguide groundplanes. The substrate need not be grounded to the coaxial connector through a substrate bottom surface groundplane/chassis interface. The substrate can include signal trace layers underlying the top surface, and vias proximate to the wall assembly extensions are formed between the coplanar waveguide groundplane and underlying ground layers.
