CMOS and SiGe RFICs for Microwave, MM-Wave and THz Wafer-Scale Phased Arrays and Imaging Arrays

Wireless Communications Industry Endowed Chair Professor

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 large phased arrays on a single chip covering distinct frequency bands, from 2 GHz to > 94 GHz, using commercial CMOS and SiGe processes. Typical designs include an 8-element 8-16 GHz SiGe phased array receiver, a 16-element Tx/Rx phased array at 42-48 GHz with 5-bit amplitude and phase control, and a 16-element Rx phased array at 77-84 GHz which includes a built-in-self-test system Also, an 8-20 GHz digital beam-former chip capable of multiple beam operation and with high immunity to interferers will also be presented. IN terms of wafers-scale designs, 94 GHz and 110 GHz wafer-scale phased arrays will also be presented including high efficiency antennas. Also, a 320 GHz imaging array with record low-noise will be presented, together with a 400 GHz transmit array capable of mW EIRP power radiation. It will be shown that SiGe and CMOS can and has changed the way we think about phased arrays and imaging systems.
Gabriel M. Rebeiz (Fellow, IEEE) is the Wireless Communications Industry Chair Professor of electrical and computer engineering at the University of California, San Diego. Prior to this appointment, he was at the University of Michigan from 1988 to 2004. He received his Ph.D. from the California Institute of Technology. He has contributed to planar mm-wave and THz antennas and imaging arrays from 1988-1996, and his group has optimized the dielectric-lens antennas, which is the most widely used antenna at mm-wave and THz frequencies. Prof. Rebeiz’ group also developed 6-18 GHz and 40-50 GHz 8- and 16-element phased arrays on a single silicon chip, the first mm-wave silicon passive imager chip at 85-105 GHz, and the first phased-array chips with built-in-self-test capabilities. His group also demonstrated high-Q RF MEMS tunable filters at 1-6 GHz (Q> 200) and the new angular-based RF MEMS capacitive and high-power high-reliability RF MEMS metal-contact switches. As a consultant, he helped develop the USM/ViaSat 24 GHz single-chip SiGe automotive radar, phased arrays operating at X, Ku-Band, K, Ka, Q and W-band for defense and commercial applications, the RFMD RF MEMS switch and the Agilent RF MEMS switch.
Prof. Rebeiz is an IEEE Fellow, an NSF Presidential Young Investigator, an URSI Koga Gold Medal Recipient, the 2003 IEEE MTT (Microwave Theory and Techniques) Distinguished Young Engineer, and is the recipient of the IEEE MTT 2000 Microwave Prize, the IEEE MTT 2010 Distinguished Educator Award and the 2011 IEEE AP (Antennas and Propagation) John D. Kraus Antenna Award. He also received the 1997-1998 Eta-Kappa-Nu Professor of the Year Award, the 1998 College of Engineering Teaching Award, and the 1998 Amoco Teaching Award given to the best undergraduate teacher at the University of Michigan, and the 2008 Teacher of the Year Award at the Jacobs School of Engineering, UCSD. His students have won a total of 20 best paper awards at IEEE MTT, RFIC and AP-S conferences. He has been an Associate Editor of IEEE MTT, and a Distinguished Lecturer for IEEE MTT, IEEE AP, and IEEE Solid-State Circuits Societies.
Prof. Rebeiz has graduated 48 Ph.D. students and 16 Post-Doctoral Fellows, has more than 500 IEEE publications, and currently leads a group of 21 Ph.D. students and Post-Doctoral Fellows in the area of mm-wave RFIC, tunable microwaves circuits, RF MEMS, planar mm-wave antennas and terahertz systems. He is the Director of the UCSD/DARPA Center on RF MEMS Reliability and Design Fundamentals, and the author of the best seller book, RF MEMS: Theory, Design and Technology, Wiley (2003).
