Workshop 1.3
RF MEMS for Radar and Phased-Array Applications

Dr. Gabriel M. Rebeiz - Univ. of Michigan, Ann Arbor

Thu, 29 April 2004, 8:00 AM - 12:00 PM


The development of RF MEMS switches has accelerated considerably over the past several years, and currently there are several switches which have been tested to 50-100 billion cycles with no failures. RF MEMS capacitive and metal-contact switches can now handle Watts of RF power at 10 GHz and this is ideal for most radar applications. RF MEMS phase shifters have also been demonstrated from 5 GHz to 110 GHz, with a loss of 0.25 dB/bit at 10 GHz and 0.7 dB/bit at 94 GHz. This results in 4-bit phase shifters with only 1.0 dB on-wafer loss at 10 GHz and 2.8 dB loss at 94 GHz, making them very attractive for phased-array applications and more specifically, reflect arrays. However, it is still hard to package these devices, and fundamental questions regarding the need of a hermetic package are not well understood. The talk will present the latest work in high isolation RF MEMS switches, switch networks, and phase shifters, and the use of these novel devices in radar systems.

This Tutorial has a recommended book:

?RF MEMS: Theory, Design and Technology?, Gabriel M. Rebeiz, Wiley, 2003.

Dr. Gabriel M. Rebeiz - Univ. of Michigan, Ann Arbor

Gabriel M. Rebeiz (Fellow, IEEE) earned his Ph.D. degree in electrical engineering from the California Institute of Technology, Pasadena, and is currently a professor of electrical engineering and computer science at the University of Michigan, Ann Arbor. His research interests include applying micro-electro-mechanical systems (MEMS) for the development of novel components and sub-systems for radars and communication systems. He is also interested in SiGe RFIC design for receiver applications, and in the development of planar antennas and microwave/millimeter-wave front-end electronics for communication systems, automotive collision-avoidance sensors, and X- to W-band phased arrays. Prof. Rebeiz was the recipient of the National Science Foundation Presidential Young Investigator Award in April 1991 and the URSI International Isaac Koga Gold Medal Award for Outstanding International Research in August 1993. Prof. Rebeiz was selected as the 1997-1998 Eta-Kappa-Nu EECS Professor of the Year. He also received the 1998 Amoco Foundation Teaching Award, given yearly to one faculty at the University of Michigan, for best undergraduate teaching. Prof. Rebeiz is the co-recipient with his student Scott Barker, of the IEEE 2000 Microwave Prize, and the IEEE MTT 2003 Outstanding Young Engineer Award.
