At the ISSCC conference in San Francisco Sony today presented details of a millimeter-wave wireless intra-connection technology that realizes 11Gbps wireless data transfer speeds inside electronic products such as television sets.
Sony’s system uses electromagnetic waves with a frequency of 30GHz to 300GHz and wavelength between 1mm and 10mm.
Specifically, Sony has integrated energy efficient millimeter-wave circuits on 40nm CMOS LSIs, with an active footprint of just 0.13 square mm including both the transmitter and receiver.
Since the Sony system has a range of only 14mm its application will be limited to intra-IC connections. Still, by replacing wires and internal circuitry with wireless connections, this technology should enable a reduction in the size and cost of ICs and other components used in electronic products.
