Abstract:                         The talk will present the phased-array
effort at UCSD. Rebeiz and his colleagues 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 array at 90-100 GHz. The talk will cover
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 of built-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 are presented as a way to replace phased
arrays in certain applications. The discussion will also cover a family
of high-efficiency silicon on-chip antennas with more than 50%
efficiency at 60-120 GHz, which are essential for wafer-scale
transceiver and phased-array integration.

 

Bio:                                  Rebeiz, an IEEE Fellow, received
his Ph.D. from the California Institute of Technology. Prior to his
appointment at UCSD, he was at the University of Michigan, 1988-2004. He
contributed to planar mm-wave and THz antennas and imaging arrays, and
his group has optimized the dielectric-lens antennas, the most widely
used antenna at mm-wave and THz frequencies. Rebeiz's 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. 

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, as well as the 2008 Teacher of the Year
Award at the Jacobs School of Engineering, UCSD. He has been an
associate editor of IEEE MTT, and a distinguished lecturer for IEEE MTT,
IEEE AP and IEEE SSC.

He has had more than 500 IEEE publications, and currently leads a group
of 21 Ph.D. students and postdoctoral 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).
