Abstract

Microelectronic devices, methods of operating microelectronic devices, and methods of providing microelectronic devices are described. In one embodiment, a microelectronic device includes a microelectronic package which provides a housing within which integrated circuitry is received. An integrated circuit die is received within the microelectronic package and includes integrated circuitry formed thereon. The integrated circuitry comprises first transmit/receive circuitry configured to transmit and receive radio frequency signals. Second transmit/receive circuitry is provided, discrete from the first transmit/receive circuitry, and is contained within the microelectronic package. The second circuitry is configured to transmit and receive radio frequency signals, wherein the first and second transmit/receive circuitry are configured to establish wireless communication between one another within the microelectronic package. In another embodiment, a microelectronic package is provided having housed therein integrated circuitry. Wireless communication is produced using a transmitter inside the microelectronic package. The produced wireless communication is received using a receiver inside the microelectronic package. Responsive to the receiving of such communication, the integrated circuitry is caused to operate in a designed manner.
