Abstract:
Microelectronic package communications are described that use radio interfaces that are connected through waveguides. One example includes an integrated circuit chip, a package substrate to carry the integrated circuit chip, the package substrate having conductive connectors to connect the integrated circuit chip to external components, and a radio on the package substrate coupled to the radio chip to modulate the data over a carrier and to transmit the modulated data. A waveguide connector is coupled to a dielectric waveguide to receive the transmitted modulated data from the radio and to couple it into the waveguide, the waveguide carries the modulated data to an external component.

Embodiments include a waveguide bundle, a dielectric waveguide, and a vehicle. The waveguide bundle includes dielectric waveguides, where each dielectric waveguide has a dielectric core and a conductive coating around the dielectric core. The waveguide bundle also has a power delivery layer formed around the dielectric waveguides, and an insulating jacket enclosing the waveguide bundle. The waveguide bundle may also include the power deliver layer as a braided shield, where the braided shield provides at least one of a DC and an AC power line. The waveguide bundle may further have one of the dielectric waveguides provide a DC ground over their conductive coatings, where the AC power line does not use the braided shield as reference or ground. The waveguide bundle may include that the power delivery layer is separated from the dielectric waveguides by a braided shield, where the power delivery layer is a power delivery braided foil.
