Abstract :
We present 60 GHz 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 60 GHz-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 1 Gbps in an OFDM demonstrator, which will be continuously upgraded and optimized for higher data transmission with better link adaptability.
