Patent ID: 8410874

Claim:
A coplanar waveguide (CPWG) signal transition element that transitions high-speed signals between vertically stacked coplanar waveguide transmission lines comprising: one or more dielectric layers; a plurality of electrically conductive vias extending through at least a portion of the one or more dielectric layers, the vias including one or more signal vias and one or more ground vias that are configured to transition high-speed signals between the vertically stacked coplanar waveguide transmission lines, the vias disposed in a first plane including at least one ground via and a second plane including at least two ground vias and at least one signal via, wherein the first plane is substantially parallel to the second plane; and a ground plane disposed within the one or more dielectric layers and electrically coupled to the one or more ground vias, the ground plane having one or more openings through which the one or more signal vias respectively pass.
