Abstract

This paper presents a mm-wave two-stage push-push BiCMOS frequency quadrupler for E-band wireless backhaul applications. To enhance gain-bandwidth product and overcome the limitations of classic push-push pairs, coupled resonators realized through low-k transformers are employed. A novel transformer layout is proposed for single-ended to differential conversion to achieve superior suppression of differential mismatches and enhanced gain. The measured prototype, fabricated in 55 nm BiCMOS technology, achieves a remarkable 27% fractional bandwidth around the center frequency of 74 GHz with a power consumption of 7 mW only
