The proliferation of bandwidth hungry multimedia applications has pushed the requirement for new multi-gigabit wireless solutions well beyond the gigabit per second. Similar cost structure and power consumption as current high volume wireless connectivity solutions (Wi-Fi and Bluetooth) is a requisite to address the consumer electronics market. Therefore, standard digital CMOS and plastic packaging is the only platform of choice for a successful adoption. 60GHz is today the leading technology enabling 3-5Gb/s at 3-5m, in quasi-NLOS for 200mW power budget. It offers a roadmap toward data rate beyond 15Gb/s and combined scenario with Wi-Fi. This presentation will highlight the world first highly integrated 60 GHz CMOS/PCB single-chip digital phased array solution, embedded in QFN package. This represents a unique opportunity to develop low power 60GHz multi-gigabit radio at a similar cost structure as a Bluetooth radio, addressing the needs of a multitude of bandwidth hungry wireless multimedia applications such as high definition streaming and massive side loading. The convergence of 60GHz CMOS digital radio, phased array technology, low power multi-gigabit mixed-signal processing low cost filter, phased array antenna embedded in standard package is discussed. In addition, uncompressed HDMI video streaming is demonstrated for the first time, using a standard battery (AAA) operated compact 60GHz CMOS/PCB QFN based module. These solutions offer the lowest energy per bit transmitted wirelessly at multi-gigabit rate, reported till date, to meet the very stringent low-power specifications for battery operated consumer electronic portable devices.
