Important results from the project
The project demonstrated a high‑performance CMOS mmWave power amplifier and established a robust design flow for future energy‑efficient front‑end circuits. Results include new modelling methods, successful tape‑out, several scientific publications, and strengthened academic–industrial collaboration for the collaborating partners Chalmers University of Technology and Sivers Semiconductors AB.
Expected long term effects
The project accelerates Sweden’s transition to low‑cost CMOS mmWave technology, enabling competitive 5G/6G products. The methods developed will improve design efficiency and benefit future commercial RFIC generations.
Approach and implementation
The project was planned around four work packages covering system analysis, CMOS PA design and modelling, and final characterization. After initial delays due to postdoc recruitment, the project proceeded according to a revised schedule. Chalmers focused on high‑performance, narrowband PA topologies and modelling, while Sivers developed broadband and robust implementations suited for practical 5G/6G transmitters. The collaboration worked well and the technical targets were met.
