innovation for industry

As 5G technology is deployed around the world, researchers at CEA-Leti are already designing solutions to meet the needs of 6G wireless technology. By combining existing manufacturing processes and an innovative architecture, CEA-Leti teams have successfully demonstrated a solution for D-Band (140 GHz) wireless communications.
During the IEEE Radio Wireless Week in Nevada, USA (Jan. 22-25), CEA-Leti experts will present one of the key building blocks for this innovative solution. As explained by Eric Mercier, Deputy Head of the CEA-Leti Wireless & Telecom Unit:
“By building on existing CMOS RFSOI technology, our current system can achieve very high data rates (above 100 Gb/s) at reasonable costs and energy consumption. We designed a scalable architecture that uses up to four identical integrated circuits (IC) in the 60 GHz frequency band and covers up to 16 channels. A 140GHz final stage IC converts all of the bonded channels to the D-band for both receive and transmit modes.”
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
