Energy efficient adaptive front-ends for fixed wireless access and 5G NR-U in the 57-71 GHz frequency band

Research Project, 2022 – 2024

Purpose and goal
The project´s objective is to conduct research, develop, implement and characterize a new generation of adaptive 60 GHz CMOS power amplifiers with better performance, which are more energy efficient than current BiCMOS solutions. The project targets a global market with a large growth potential among traditional broadband providers, in addition to new market segments made possible by AI/ML. Chalmers and Sivers Semiconductors contribute with complementary strengths in mm-Wave power amplifier design, market, and applications.

Expected results and effects
Sivers Wireless AB, a subsidiary to Sivers Semiconductors, and Chalmers University of Technology will collaborate in research and development of a new generation of CMOS power amplifiers for the 60-GHz mm-Wave band. The project aims to make today´s integrated radio circuits for license-free 60-GHz broadband access and 5G NR-U from Sivers Semiconductors more competitive, energy-efficient and cost-effective by applying research results in low-cost and high-volume CMOS technology, while contributing to world class research.
