Scalable 79- and 158-GHz integrated radar transceivers in SiGe BiCMOS technology

This paper presents scalable fully-integrated 79/158 GHz radar transceivers (TRX) for radar applications using a 130nm SiGe BiCMOS technology. A system concept is described enabling a flexible radar platform design. The dual-band configuration exploits the advantages of the particular frequency band and facilitates performance optimization of the radar system with respect to range resolution and dynamic range. A scalable TRX architecture enables cascading of many units thus simplifying the implementation of a MIMO radar. The use of a single 39.5 GHz local oscillator (LO) source makes the PCB design simple, even for multi-TRX radar systems.
