2022 IEEE International Symposium
on Phased Array Systems and Technology

Revolutionary Developments in Phased Arrays

11–14 October 2022

Tutorial: Full Duplex Phased Array Systems and Technologies

Many wireless systems could benefit from the ability to transmit and receive on the same frequency at the same time, which is known as in-band full-duplex (IBFD) and/or simultaneous transmit and receive (STAR). This technology could lead to enhanced spectral efficiency for future wireless networks, such as fifth-generation New Radio (5G NR) and beyond, and/or could enable capabilities and applications that were previously considered impossible, such as IBFD with phased array systems. In this workshop, experts from academic and federal research institutions will discuss the various approaches that can be taken to suppress the inherent self-interference that is generated in IBFD phased array systems, and will present both static and adaptive techniques that span across the propagation, analog and digital domains. Presentations will contain details and measured results that encompass unique array topologies, RF cancellation and other isolation methods as well as advances in adaptive beamforming and digital filtering. Throughout this workshop, state-of-the-art IBFD phased array systems that utilize these technologies will be provided as practical examples for various applications.

Harish Krishnaswamy (Senior Member, IEEE)

Harish Krishnaswamy received the B.Tech. degree in electrical engineering from IIT Madras,
Chennai, India, in 2001, and the M.S. and Ph.D. degrees in electrical engineering from the University of Southern
California (USC), Los Angeles, CA, USA, in 2003 and 2009, respectively.

In 2009, he joined the Electrical Engineering Department, Columbia University, New York, NY, USA, where he is currently an Associate Professor and the Director of the Columbia High-Speed and Millimeter-Wave IC Laboratory (CoSMIC). In 2017, he co-founded MixComm Inc., Chatham, NJ, USA, a venture-backed start-up, to commercialize CoSMIC
Laboratory’s advanced wireless research. MixComm Inc. signed a definitive agreement to be acquired by Sivers
Semiconductors for $155M in October 2021. His research interests include integrated devices, circuits, and systems for a variety of RF, millimeter-wave (mmWave), and sub-mmWave applications.

Dr. Krishnaswamy was a recipient of the IEEE International Solid-State Circuits Conference Lewis Winner Award for
Outstanding Paper in 2007, the Best Thesis in Experimental Research Award from the USC Viterbi School of Engineering
in 2009, the Defense Advanced Research Projects Agency Young Faculty Award in 2011, the 2014 IBM Faculty Award, the Best Demo Award at the 2017 IEEE ISSCC, the best student paper awards at the 2015, 2018, and 2020 IEEE Radio
Frequency Integrated Circuits Symposium and the 2020 IEEE International Microwave Symposium, the 2021 IEEE MTT-S
Microwave Magazine Best Paper Award, and the 2019 IEEE MTT-S Outstanding Young Engineer Award. He has been a
member of the technical program committee of several conferences, including the IEEE International Solid-State Circuits Conference since 2015 and the IEEE Radio Frequency Integrated Circuits Symposium since 2013. He has also served as a Distinguished Lecturer for the IEEE Solid-State Circuits Society and is a member for the DARPA Microelectronics Exploratory Council.
