Abstract

A millimeter-wave wireless data transmission link is utilized to interconnect multiple electronic components within an enclosed electronic system. More specifically, an electronic apparatus includes a housing, a plurality of separated electronic components located within the housing, and a plurality of millimeter-wave transmit/receive integrated circuit devices, each coupled to a corresponding one of the separated electronic components. Data is transmitted between the plurality of separated electronic components via the millimeter-wave transmit/receive integrated circuit components, each of which includes one or more transmit/receive circuits preferably operating at frequencies above 35 GHz. The transmit and receiving frequencies of the transmit/receive integrated circuit devices can be dynamically set in memory to enable transmission links to be easily reconfigured.
