Professor

As wireless communication technologies continue to advance, highly reconfigurable RF front ends are
increasingly required to support greater system flexibility, compactness, and intelligence. Bandpass filters
(BPFs), which are essential for suppressing unwanted signal interference, can further enhance system
efficiency when integrated with reconfigurable and multifunctional capabilities. Meanwhile, increasingly
stringent system SWaP requirements, including size, weight, and power, are driving the need for
miniaturized on-chip implementations of these filters. This presentation will discuss the development of
various reconfigurable multifunctional filters and their miniaturized on-chip realizations, including
reconfigurable filtering couplers, filtering phase shifters, and filtering beamforming networks.
Representative examples will be provided to illustrate the design principles, implementation methods, and
potential applications in wireless communication systems

Biography:

Tao Yang received his B.Eng. and Ph.D. degrees from the University of Electronic Science and Technology of
China (UESTC), Chengdu, China, in 2005 and 2011, respectively. He is currently a full professor at UESTC.
From January 2016 to September 2017, he worked as an R&D IC engineer with Broadcom Ltd. in San Jose,
CA, focusing on RF filter designs using FBAR technology and PA-filter module designs. Between April 2014
and February 2016, he was a senior hardware engineer at Qualcomm Inc., San Diego, CA, where he worked
on RF passive component development using CMOS and SOI technologies. From October 2012 to April
2014, he was with the Department of Electrical and Computer Engineering at the University of California,
San Diego (UCSD), working on tunable RF microwave circuits and systems. Prior to that, from August 2011
to September 2012, he served as a scientific researcher at Université de Rennes 1, Rennes, France. He also
spent time as a visiting scholar at the University of California, Los Angeles (UCLA), from September 2008 to
September 2010. Prof. Yang’s research interests include reconfigurable microwave and millimeter-wave
circuits and systems, metamaterial-based microwave circuits, the design and development of RF
components for highly integrated RF ICs using CMOS, SOI, GaAs, and GaN technologies, as well as the
development of high-Q film bulk acoustic resonators (FBARs) and filters. He has authored over 100 journal
and conference papers and currently serves as an Associate Editor for IEEE Transactions on Microwave
Theory and Techniques.
