Abstract
An apparatus for the transfer of broadband, high-frequency signals of a center wavelength (λc), including a conductor structure, which includes at least one signal path and two reference paths arranged symmetrically to the signal path. Together the conductor structure and the two reference paths form a coplanar line, with the conductor structure being arranged on two oppositely lying sides of at least one dielectric substrate layer of a predetermined thickness in such a manner that the conductor structure overlaps in predetermined coupling regions, whereby the coupling region of the conductor structure transfers the high-frequency signals by an electromagnetic coupling, wherein the thickness of the substrate layer (18) is smaller than λc/4, and wherein multiple electromagnetic couplings are arranged serially one after the other. The apparatus enables a galvanic isolation having good transfer properties in the case of frequencies greater than 6 GHz.
