The global market for next-generation telecommunications systems (B5G, 6G) demands products with higher speeds, better energy efficiency and sufficient power output. The project aims to meet these needs by developing and industrializing next-generation semiconductor technologies (SiGe BiCMOS for ST, RF GaN for UMS) and the associated integrated circuit design and characterization environments. Innovative analog and digital RF integrated circuits will be designed with the technologies developed and integrated as ‘FEM’ modules of innovative telecommunications system demonstrators. New assembly techniques that can solve RF signal integrity and heat dissipation issues, or greatly simplify RF systems, will also be explored. Demonstrators of innovative telecommunications systems will be developed (10 demonstrators; by NOKIA, SAFRAN, SIAE, and other partners), to validate new semiconductor and assembly technologies, on use cases envisaged for wireless B5G/6G networks (more particularly for network access and network trunks), very high-speed optical networks, and Earth observation and satellite telecommunications. The SHIFT consortium brings together players covering the entire value chain of these telecommunications applications, from laboratories to manufacturers, thus guaranteeing the highest scientific level and the possibility of validating the work carried out on suitable demonstrators. Activities will include environmental and economic impact assessments.
