Abstract
A transition unit of a radio frequency device provides a transition between a planar differential pair transmission line and a hollow radio frequency waveguide. It comprises a substrate layer arrangement with a planar differential pair transmission line arranged on one or more surfaces of at least one substrate layer, whereby an end section of the differential pair transmission line is configured as a radio frequency signal transition pattern. It further comprises an end section of a waveguide that is attached to the substrate layer arrangement and that superposes the radio frequency signal transition pattern. The waveguide is directed perpendicular to the substrate layer arrangement. An open end of the end section of the waveguide is attached to a first outer surface or a second outer surface of the substrate layer arrangement. The transition pattern comprises open loop shaped end sections of a first and second transmission line segment.
