A contribution to Europe's desire for sovereignty in the semiconductor sector.
Supported by 43 partners, SHIFT wants to bring important contributions to “double transition”, thanks to innovations in composants and advanced telecommunications systems technologies. The SHIFT consortium will develop innovative semiconductors technologies and casing and will validate them thanks to demonstrators in telecommunications fields such as wireless 5GNR (Beyond 5G) an 6G network access, very high-speed optical links between servers, satellite telecommunications and Eath observation.
SHIFT will contribute to social en environmental concerns, with an analysis of telecommunications products’ cycle of life, through their production line, their operational use and their recycling process. Finally, the SHIFT project supports the Europe’s desire for sovereignty in the semiconductor sector, accelerating the new european technologies development distribution, and allowing numerous young engineers and researchers to follow a training, thanks to more recent results. Thus, SHIFT is an ambitious project concerning sustainable development for innovative european companies.
In this context, JUNIA’s activity is focused on conception and validation of circuits for future axée sur la conception et la validation of circuits for future transceivers in the sub-10GHz band in a MIMO system. The MIMO technology (Multiple Input Multiple Output) consists in transmitting simultaneously serveral information feed on several transmitting antennas, in order to increase base station capacity to improve the customer experience. The developped circuit targets very dense MIMO networks (mMIMO) with up to 256 antennas.
We are contributing to the development of a radiofrequences « System on Chip » (RF SoC) dedicated to the emission part, in partnership with Nokia Bell Labs France, Seamless Waves, Télécom Paris and IMS Bordeaux. This SoC integrates a chip with the CMOS technology allowing the digital signal processor (DSP), its transfer to radiofrequences with a sigma-delta convertor (SD) and finally its analogue conversion (RF DAC) to drive a BiCMOS chip which includes the power amplifiers connected to the antennas. The CMOS chip also includes a radiofrequences analogue/digital conversion (RF ADC) for tracking the transmitted signal. The whole system is controlled by a set of digital functions implemented in an FPGA.
SHIFT is financed by Key Digital Technologies Joint Undertaking (KDT JU) – the public-private partnership for research, development and innovation as part of Horizon Europe – and by the national autorities as part of the n° 101096256 subvention convention.
