Abstract ■

To enable mass-market applications based on short-range wireless communication around 60 GHz at datarates above 1 Gbps, cheap implementation technologies are needed. The radios for these applications often use antenna arrays with beamforming to improve the link budget. This work discusses the state-of-the-art on CMOS beamforming architectures and describes the different parts of a wireless link that is built around a four-antenna array on a PCB that also contains 45nm digital CMOS receiver ICs with beamforming capabilities.
