60GHz OFDM hardware demonstrators in SiGe BiCMOS: State-of-the-art and future development

Abstract

We present 60GHz OFDM hardware demonstrators developed so far and outline design considerations for future developments. OFDM schemes have been developed to combat multi-path interferences in indoor wireless environments and further optimized for multi-gigabit data transmission in 60GHz-band. RF and IF analogues front-ends (AFEs) have been developed with high-speed SiGe BiCMOS technologies. Future developments on AFE are mainly devoted to one-chip integration of RF and IF components based on a sliding IF architecture. We have already achieved wireless transmission of about IGbps in an OFDM demonstrator, which will be continuously upgraded and optimized for higher data transmission with better link adaptability.
