New low-voltage W-band millimeter-wave technology; applicable for cars, bikes, cellphones

Green Car Congress

Details of the technology are being presented this week at the IEEE Radio Frequency Integrated Circuits Symposium (RFIC) 201 in Honolulu, Hawaii. Given the fact that even cars are becoming battery-operated, it is imperative that these circuits be low-power. The W-band covers the frequencies used by automotive radars.
