报告题目：Radio Frequency Microsystems for 5G and IoT Inspired Front-end Signal Processing
报告摘要：Recently, 5G and IoT have sparked great research interest in developing the next generation front ends that can meet the more stringent requirements on performance, frequency scalability, bandwidth, power consumption, and spectral utilization efficiency. This talk will discuss several new types of RF micro-systems that can enable either conventional signal processing functions (e.g., filtering and impedance transformation), or new ones (e.g., RF correlation and non-reciprocity) with unprecedented performance specifications for 5G and IoT applications. Specifically, the most recent development on MEMS resonators, transformers, chirp compressors, gyrators, and circulators will be first presented and followed by the discussions on overcoming the remaining technology bottlenecks in their paths to commercialization.
Prof. Songbin Gongreceived the Ph.D. degree in electrical engineering from the University of Virginia, Charlottesville, VA, USA, in 2010. He is currently an Assistant Professor and an Intel Alumni Fellow with the Department of Electrical and Computer Engineering and the Micro and Nanotechnology Laboratory, University of Illinois at Urbana–Champaign, Urbana, IL, USA. His research primarily focuses on design and implementation of RF-MEMS devices, components, and subsystems for reconfigurable RF front ends. In addition, his research explores hybrid microsystems based on the integration of MEMS devices with photonics or circuits for imaging sensing and signal processing. He is a recipient of the 2014 Defense Advanced Research Projects Agency Young Faculty Award and the 2017 NASA Early Career Faculty Award. Along with his students and postdocs, he received the Best Paper Award from the 2017 IEEE International Frequency Control Symposium and the 2nd place in the Best Paper Competition at 2018 International Microwave Symposium. He has been a guest editor for the special issue on RF-MEMS in the Journal of Micromechanics and Microengineering, and also a Technical Committee Member of MTT-21 RF-MEMS of the IEEE Microwave Theory and Techniques Society, International Frequency Control Symposium, and International Electron Devices Meeting.
