Abstract
A direct-conversion micromixer realized in a modern SiGe:C bipolar technology for application in automotive radar systems at 77 GHz is presented. The mixer exhibits a minimum conversion gain of 15 dB and a maximum noise figure of 16.5 dB over a frequency range from 75 GHz to 85 GHz. The 1dB input related compression point is at -3dBm and the RF and LO matching is better than -20 dB and -10 dB, respectively. The total DC current consumption is 34 mA at 5.5 VKeywords
