RADLAB Seminar

CMOS and SiGe RFICs for Microwave and MM-Wave Phased Arrays

Professor Gabriel M. RebeizUniversity Of California, San Diego

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. It will be shown that SiGe and CMOS has changed the way we think about phased arrays and imaging systems.

Prof. Gabriel Rebeiz is Distinguished Professor and the Wireless Communications Industry Endowed Chair at the University of California, San Diego. He is an IEEE Fellow, an NSF Presidential Young Investigator, an URSI Koga Gold Medal Recipient, IEEE MTT 2003 Distinguished Young Engineer, and is the recipient of the IEEE Daniel E. Nobel Medal (Field Award), the IEEE MTT Microwave Prize (2000 and 2014), the IEEE MTT 2010 Distinguished Educator Award and the IEEE Antennas and Propagation 2011 John D. Kraus Antenna Award. He is also the recipient of the 1998 Amoco Teaching Award given to the best undergraduate teacher at the University of Michigan, and the 2008 Jacobs ECE Teacher of the Year Award at UCSD. His group has lead the development of complex RFICs for phased array applications from X-band to W-band, culminating recently in wafer-scale integration with high-efficiency on-chip antennas. His phased array work is now used by most companies developing complex communication and radar systems. He has graduated 55 PhD students and 20 post-doctoral fellows, and currently leads a group of 15 PhD students in mm-wave RFIC, planar mm-wave antennas and terahertz systems, microwave circuits, RF MEMS, tunable networks, and is the Director of the UCSD/DARPA Center on RF MEMS Reliability and Design Fundamentals.
