A microelectronic package is described with a wireless interconnect for chip-to-chip communication. In one example, the package 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, a radio coupled to the integrated circuit chip to receive data from the integrated circuit chip and modulate the data onto a radio frequency carrier, and an antenna on the package substrate coupled to the radio to send the modulated data over the carrier to an external device.
