1. An RF multilayer circuit board comprising:

  • a first conductive device in a first plane for providing a first RF signal line;

    a first reference potential plane in a second plane for providing a reference potential of the first RF signal line;

    at least one second reference potential plane in a third plane for providing a reference potential of an at least second RF signal line;

    at least one second conductive device in a fourth plane for providing a second RF signal line;

    a plated through hole device for electrically connecting the first and second conductive devices, the first and second reference potential planes between them each having a recess in an area of the plated through hole device; and

    at least one additional conductive device in the area of the plated through hole device at least between the first and second reference potential planes and bonding them in order to provide a waveguiding channel around the plated through hole device.
