SHIFT Workshop Recent Advances in Millimeter-Wave and 6G Hardware Design Using BiCMOS and SiGe Technologies

The SHIFT Consortium organised the second workshop for a wide and impactful dissemination of the SHIFT results and outreach to stakeholders. The workshop was organised during the 52^nd European Solid-State Electronics Research Conference (ESSERC 2026) in Mallorca, Spain. Taking place on the 7^th of September 2026, this Workshop was a highly interesting opportunity to present the results obtained in the context of the SHIFT project.

This workshop focuses on recent advances in millimeter-wave and 6G hardware design using BiCMOS and SiGe technologies, within the framework of the SHIFT Chips EU Project (Sustainable tecHnologies enablIng Future Telecom applications). Overall, it provides a comprehensive overview of enabling technologies for next-generation high-frequency communication systems. It emphasizes system-level optimization through co-design of circuits, antennas, and signal processing. Following circuits design are addressed:

• Ultra-low-jitter frequency generation techniques achieving record performance for high spectral purity applications.

• Novel modeling and design approaches for coupled lines that enable compact and efficient D-band components.

• Multi-antenna transceivers leveraging spatial processing, presented to relax system constraints and improve performance.

• Integration challenges through compact Ka-band front-end modules combining SiGe and GaN technologies.

• Advanced low-noise amplifier (LNA) design methodologies in 55-nm BiCMOS, including modeling and measurement insights.

• Power amplifier (PA) designs trade-offs for 6G FR3 systems, covering efficiency, linearity, and stability.
