FirstTo6G is developing the world’s first 6G transceiver microchip technology, comprising data converters and corresponding millimetre-wave front-ends that meet the stringent requirements necessary for the widespread adoption of 6G. The project is focused on developing energy-efficient data converters capable of achieving up to 16GHz instantaneous bandwidth and integrating state-of-the-art frontend technology. These converters will be integrated into two complete millimetre-wave transceiver chipsets.
The project’s architecture involves integrating groundbreaking Fourier Domain Digital-to-Analog and Analog-to-Digital Converters (FDDACs/FDADCs) with novel frontend technologies. FirstTo6G will develop two demonstrators, as depicted in the figure. The proposed V-band solution aims to integrate the complete transceiver into a single 22nm-FDSOI-based chip, resulting in a total instantaneous bandwidth of 8GHz. The proposed D-band solution proposes a two-chip solution, with data converters in 22nm FDSOI and the frontend in silicon-based and III-V semiconductor technologies, achieving an instantaneous bandwidth of 16GHz.
Through this project, FirstTo6G addresses critical technological challenges associated with the global introduction of 6G by 2030, including high instantaneous bandwidth, energy efficiency, cost-effectiveness, and scalability. The project’s outcomes will contribute to 6G standardisation, and the demonstrators can be utilised in experimental radio devices for 6G trials. A successful adaptation of the technology developed in this project will facilitate the widespread adoption of 6G, thereby ensuring the availability of ultrahigh-speed wireless connectivity globally. Smart cities will be equipped with the capability to optimise traffic flow through continuous data exchange between vehicles, roads, pedestrians, and traffic lights. Smart energy grids will be able to distribute energy based on demand, and autonomous drones will monitor infrastructure. AR/VR applications will attain unprecedented levels of resolution and realism, benefiting from enhanced sensing capabilities and becoming an integral part of our daily lives, providing immersive mixed-reality experiences wherever we are.
