Abstract
A device includes a multilayer substrate having a first surface and a second surface opposite the first surface. An integrated circuit is mounted on the second surface of the multilayer substrate, the integrated circuit having transmission circuitry configured to process millimeter wave signals. A substrate waveguide having a substantially solid wall is formed within a portion of the multilayer substrate perpendicular to the first surface. The substrate waveguide has a first end with the wall having an edge exposed on the first surface of the multilayer substrate. A reflector is located in one of the layers of the substrate and is coupled to an edge of the wall on an opposite end of the substrate waveguide.
