Abstract:

Frequency-agile circuits and systems enable next-generation radios with reduced SWaP (size, weight, and power). Tunable low-loss microwave filters are very critical components in a frequency-agile system, yet representing the most challenging technology. Semiconductors, ferroelectric materials, ferromagnetic materials, and RF MEMS have been used to realize tunable filters. This talk will review these different techniques and focus on the state-of-the-art technology of using RF MEMS devices in tunable microwave filters.

Biography:

Xun Gong (S’02-M’05) received the B.S. and M.S. degrees in electrical engineering from FuDan University, Shanghai, P.R. China, in 1997 and 2000, respectively, and the Ph.D. degree in electrical engineering from The University of Michigan at Ann Arbor in 2005.

He is currently an Assistant Professor of Electrical Engineering and Computer Science (EECS) at University of Central Florida (UCF) and Director of the Antenna, RF and Microwave Integrated systems (ARMI) Laboratory. He worked at Air Force Research Laboratory (AFRL) in Hanscom, MA in 2009 under the support of Air Force Office of Scientific Research (AFOSR) Summer Faculty Fellowship Program (SFFP). He was with the Birck Nanotechnology Center at Purdue University, West Lafayette, IN, as a Post-Doctoral Research Associate in 2005. His research interests include high-Q resonators and filters, microwave sensors, antennas, phased arrays, integrated RF front-end, flexible electronics, and packaging.

Dr. Gong is a member of the International Microelectronics and Packaging Society (IMAPS). He has served on the Editorial Boards of IEEE Transactions on Microwave Theory and Techniques (MTT), IEEE Transactions on Antennas and Propagation (AP), IEEE Microwave and Wireless Component Letters (MWCL), and IEEE Antennas and Wireless Propagation Letters (AWPL). He has been the IEEE AP/MTT Orlando Chapter Chair since 2007. He has been the recipient of the NSF Faculty Early CAREER Award in 2009. He received the Outstanding Undergraduate Teaching Award in EECS School at UCF in 2009. He is the recipient of Outstanding Engineer Awards from IEEE Florida Council and Orlando Section, respectively, in 2009. He is the recipient of the Third Place Award in the Student Paper Competition presented at the 2004 IEEE MTT-S International Microwave Symposium (IMS), Fort Worth, TX.
