Short bio of the Speaker:

Bodhisatwa Sadhu received the B.E. degree in Electrical and Electronics Engineering from BITS-Pilani, India in 2007, and the Ph.D. degree in Electrical Engineering from the University of Minnesota, Minneapolis, in 2012. He has been with IBM T. J. Watson Research Center, NY since 2012 where he is currently a Senior Research Scientist. He was an Adjunct Assistant Professor at Columbia University in New York from 2017 to 2020. He has authored and co-authored 60+ peer-reviewed papers, the book Cognitive Radio Receiver Front-Ends (Springer, 2014), and several book chapters. He also holds 70+ issued U.S. patents. He serves as an IEEE Distinguished Microwave Lecturer (2021-present), Sub-committee Chair and Steering Committee Member of IEEE RFIC Symposium (2017-present), TPC member of IEEE ISSCC (2020-present), and has served as Guest Editor of IEEE TMTT in 2021 and IEEE JSSC in 2017. Dr. Sadhu is the recipient of the 2022 IEEE MTT-S Outstanding Young Engineer Award, the 2017 IEEE ISSCC Best Paper Award, the 2017 IEEE JSSC Best Paper Award, the 2017 IBM Pat Goldberg Memorial Award or the best paper in computer science, electrical engineering, and mathematics published by IBM Research and five IBM Outstanding Technical Achievement Awards. He won the BITS Pilani Silver Medal in 2007 (2nd in engineering class of 1000+ students), and stood 2nd in India in the Indian School Certificate (ISC) examination in 2003. He was recognized as an IBM Master Inventor in 2017 and 2021 (3-year terms each), and selected by the National Academy of Engineering for its Frontiers of Engineering Symposium in 2020.

 

Abstract of the talk: 

5G relies on millimeter-wave phased arrays to achieve high data rates and low latency. The majority of the 5G millimeter-wave infrastructure will be partially or completely based on silicon technology. This talk will discuss key aspects of silicon-based millimeter-wave phased-array module design and characterization. It will cover the history and fundamentals of millimeter wave and phased arrays, provide an overview of phased array antenna modules using silicon technology, and take a deep dive into an example 5G phased array antenna module. The talk will end with a peek into the future of millimeter-wave directional communications for 6G and beyond.
