6GWFF 2021 - Achieving real 100Gbps 6G/THz wireless communication (Keynote 2) - Ullrich Pfeiffer

https://www.6gwff.org/ Speaker: Ullrich Pfeiffer, University of Wuppertal, Germany Abstract: The terahertz frequency range provides abundant bandwidth (25GHz ~ 50 GHz) to achieve ultra-high-speed wireless communication and enables data rates up to and above 100 Gbps. In this talk, I will present our early work on 6G wireless transceivers and discuss their performance and link impairments. I start with link budget considerations and addresses design trade-offs with respect to the used technology. The radio front-ends are manufactured in a SiGe BiCMOS 0.13um technology and operate at a tunable carrier of 220–260 GHz. The modules achieve data-rates from 20 to 100 Gbps with an EVM from 7% to 17% at a 1-meter distance using 16-QAM. I will further present our work on polarization diversity MIMO systems above 200 GHz. The MIMO link is established using a circular dual-polarization Tx and a dual-polarization Rx module. The polarization-diversity (left-handed circular polarization and right-handed circular polarization) is provided by a lens-coupled circularly polarized on-chip antenna. With this system, two independent data-streams of 55 Gb/s each were transmitted in parallel over a 1-meter line-of-sight distance, achieving an aggregated record data-rate of 110 Gbps. Bio: Ullrich Pfeiffer received the Ph.D. in physics from the University of Heidelberg, Germany, in 1999. Till 2006 he was with the IBM T.J. Watson Research Center where his research involved RF circuit design and packaging for 60GHz communication. Since 2008 he holds the High-frequency and Communication Technology chair at the University of Wuppertal, Germany. His current research activities include the design of silicon integrated circuits for THz applications. Prof. Pfeiffer is an IEEE Fellow and an ERC Advanced Grant recipient. Among other awards, he is the recipient of the 2007 European Young Investigator Award, the co-recipient of the 2004 and 2006 Lewis Winner Award, as well as the 2012 and 2018 Jan Van Vessem Award at the ISSCC Conference. In 2017 he received the Microwave Prize. He was an IEEE SSCS Distinguished Lecturer and served as a Scientific Advisory Board Member of the Academy of Finland’s Flagship Program 6Genesis. He is an Associate Editor of the IEEE Transactions on Terahertz Science and Technology, has authored and co-authored 200+ publications, and has been the co-inventor of 10+ US and international issued patents, relating to RF, millimeter-wave, terahertz communication/imaging circuits and sensors.
