摘要： A transition unit (2) of a radio frequency device (1) provides a transition between a planar differential pair transmission line (7) and a hollow radio frequency waveguide (15, 27). The transmission unit (2) comprises a substrate layer arrangement (3) with a planar differential pair transmission line (7) arranged on one or more surfaces (10, 11) of at least one substrate layer (4, 5) of the substrate layer arrangement (3), whereby an end section (12) of the differential pair transmission line (7) is configured as a radio frequency signal emission pattern (13). The transition unit (2) further comprises an end section (14) of a waveguide (15) for radio frequency electromagnetic waves that is attached to the substrate layer arrangement (3) and that superposes the radio frequency signal emission pattern (13). The waveguide (15) is directed perpendicular to the substrate layer arrangement (3). An open end (17) of the end section 14) of the waveguide (15) is attached to a first outer surface (16) or a second outer surface (19) of the substrate layer arrangement (3). Opposite to the end section (14) of the waveguide (15) a back cavity (18) is attached with an open end (21) of the back cavity (18) towards the substrate layer arrangement (3), whereby the back cavity (18) prevents a part of the radio frequency signal emission that is emitted from the emission pattern (13) from leaking outside of the end section (14) of the waveguide (15).

摘要： A transition unit (1) providing a radio frequency signal transition between a radio frequency hollow waveguide system (2) and a planar transmission line (3) comprises two or more transition sections of transmission line (3) that are arranged adjacent to each other at a first surface (14) of the first substrate layer (4) of a substrate layer arrangement (15). The hollow waveguide system (2) comprises a distribution section wherein one input waveguide (5) is separated into one dedicated output waveguide (10) for each of the transition sections. For each of the transition sections of the transmission lines (3) a corresponding end section (11) of a respective output waveguide (10) is directed perpendicular to the first surface (14) of the first substrate layer (4). For each end section (11) an open end of the end section (11) of the waveguide system (2) superposes the corresponding transition section, and the two or more end sections (11) of the waveguide system (2) are arranged adjacent to each other in order to provide for favorable boundary conditions for electromagnetic wave propagation that result in reduced radio frequency signal power leakage from the transition unit (1) when compared to a transition unit with only one single end section (11) of the waveguide system (2).
