Abstract:This talk will present the latest work on microwave and mm-wave phased arrays and imaging systems at UCSD. The talk shows that one can build very large phased arrays on a single chip covering distinct frequency bands, from 2 GHz to > 60 GHz, using the IBM 8RF, 8HP and the Jazz SiGe18HX processes. The results show state-of-the-art performance, and all the work is done at the RF level and not a single mixer is used, leading to conceptually very simple designs which have a very wide bandwidth. Typical designs include an 8-element 8-16 GHz SiGe phased array receiver, a 16 element 30-50 GHz SiGe transmit phased array, a miniature (< 3mm2) and low power (<100 mW) CMOS phased array receiver at 24 GHz, and a 4-element SiGe/CMOS phased array at Ka-Band frequencies. Also, a W-band imaging system for security systems will be shown based on SiGe RFICs. The talk will conclude with antenna technology and new array architectures (multiple beams, multiple polarizations) which can be achieved with this level of integration.
