122-GHz chip-to-antenna wire bond interconnect with high repeatability

This paper presents a 122-GHz chip-to-antenna wire bond interconnect for low-cost, fully integrated transceivers. It is based on the standard ball-stitch bond technology and uses planar transmission lines for matching. A study on the effects of process tolerances is given. Finally, an antenna which is integrated into a QFN plastic package is characterized together with the chip-to-antenna interconnect.
