摘要

This brief presents a broadband D-band down-conversion mixer in a cost efficient 130nm SiGe BiCMOS technology with a ft/fmax of 250/370GHz from Infineon Technologies AG. The proposed mixer covers the entire D-band with a 32dB peak conversion gain and a 3dB bandwidth of 35GHz at a measured noise figure between 9.5 and 12dB in the specified band while consuming only 65mW DC power. To achieve large R...
