Advanced SiGe and CMOS Phased Arrays: Chips, Packaging, Built-In-Self-Test and Wafer-Scale Integration with High-Efficiency On-Chip Antennas

Calit2 Auditorium

EECS Distinguished Lecture Series

Speaker: Prof. Gabriel Rebeiz

Wireless Communications Industry Chair Professor

Dept. of ECE, University of California, San Diego



Refreshments will be available at 2:30PM



The talk will present the phased array effort at UCSD. We have been working in this area since 2002 and have developed state-of-the-art chips from X-band to W-band, including an 8 element 6-18 GHz phased array receiver, a 16 element Tx/Rx array at 40-50 GHz, and recently, a 9-element and a 16-element wafer-scale phased arrays at 90-100 GHz. The talk will discuss the different phased array architectures, phase shifters choices, and the required packaging to achieve a high-performance design. Other discussion topics will be the use build-in-self-test to drastically reduce the cost of phased array testing and calibration. Also, a switched-beam system and high gain Yagi-Uda antennas together with low loss SPDT and SP4T switches is presented as a way to replace phased arrays in certain applications. We will also cover a family of high-efficiency silicon on-chip antennas with > 50% efficiency at 60-120 GHz which are essential for wafer-scale transceiver and phased array integration.

Bio

Gabriel M. Rebeiz (Fellow, IEEE) is the Wireless Communications Industry Chair Professor of electrical and computer engineering at UCSD. 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, and the first mm-wave silicon passive imager chip at 85-105 GHz. 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 and W-band for defense and commercial applications, the RFMD RF MEMS switch and the Agilent RF MEMS switch. He is considered as one of the fathers of RF MEMS, tunable networks in cell phones, and phased-array RFICs.



Prof. Rebeiz is an NSF Presidential Young Investigator, an URSI Koga Gold Medal Recipient, the IEEE MTT 2003 Distinguished Young Engineer, and is the recipient of the IEEE MTT 2000 Microwave Prize, the IEEE MTT 2010 Distinguished Educator Award and the IEEE AP 2011 John D. Kraus Award. He also received the 1998 Eta-Kappa-Nu Professor of the Year 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 19 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 SSC.

Prof. Rebeiz has graduated 42 PhD students and 15 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 book, RF MEMS: Theory, Design and Technology, Wiley (2003).
