“Integrated transceivers for millimeter-wave high data-rate communications”
Abstract: The recent progress of semiconductor and integration technologies enabled the design and demonstration of high-performance and miniature millimeter-wave transceiver systems with applications in a variety of domains such as wireless communications, radars, remote sensing, or imaging. These applications are currently emerging in frequency bands spanning from 30 GHz up to 300 GHz or even 1 THz. In each case, the integration of transceiver modules combining antennas and RF integrated circuits in a single chip or package plays a critical role in meeting the application requirements in terms of budget link, power consumption, size and cost. This presentation will focus on 60-GHz technologies, which will be used in multiple applications spanning from short-range indoor device-to-device communications, outdoor mobile access for future cellular wireless networks, or long-range point-to-point communications. The main technologies and challenges involved in the development of cost-effective integrated communication modules will be presented along with state-of-the-art demonstrations and recent achievements at CEA-LETI.

Laurent Dussopt received the M.S. and Agrégation degrees in electrical engineering from the Ecole Normale Supérieure de Cachan, France, the Ph.D. degree in electrical engineering from the University of Nice-Sophia Antipolis, France, and the “Habilitation à Diriger des Recherches” degree from the University Joseph Fourier, Grenoble, France. During his PhD thesis, he developed several concepts of reconfigurable antennas and oscillating antenna arrays for wireless communications. From 2000 to 2002, he was a Research Fellow with The University of Michigan at Ann Arbor where he worked on RF-MEMS tunable capacitors, reconfigurable filters and phase-shifters at microwave and millimeter-wave frequencies. Since 2003, he is a research engineer and project leader at CEA-LETI, Grenoble, France. His research interests include UHF-RFID technologies, reconfigurable antennas, millimeter-wave integrated antennas and antenna arrays, RF-MEMS devices and systems. Since 2013, he is chief scientist of the Systems and Solutions Integration Department at CEA-LETI.
