Abstract: A waveguide launch system configured for translating radio frequency signal waves is provided. The system comprises a first printed circuit board lamina comprising an electrically conductive ground member and configured for attachment of a separate waveguide element, having a first cross-section area, thereto. A second printed circuit board lamina comprising an electrically conductive backshort cover configured to reflect the RF signal waves is bonded to a first printed circuit board lamina. An electrically conductive barrier arrangement extends through the second printed circuit board lamina. The electrically conductive barrier arrangement and the electrically conductive backshort cover form an integrated electrically conductive backshort volume of an integrated backshort having a second cross-section area. The second cross-section area is smaller than the first cross-section area.
