SiGe HBT for mm-Wave and THz Applications

Integrated circuit designs beyond 100GHz are recently researched for beyond-5G technologies. Large scale phased arrays and MIMO systems are aimed for very large data rates and very high accuracy localization. In this presentation circuit topologies and techniques are presented aiming for large RF bandwidth systems, discussing as well the possible accompanied performance limitations. System demonstrators above 100GHz will elaborate the circuits performance fully integrated in the 130nm SiGe:BiCMOS technology from IHP.
