Abstract

This paper presents a modified Gilbert type mixer which is fabricated in a 200 GHz f_T SiGe:C bipolar technology and well suited for 77 GHz bi-static automotive radar applications. The measured single sideband noise figure (NF_SSB), conversion gain (CG), and input-referred 1 dB compression point (ICP) of this mixer are 10.8 dB, 21.5 dB, and -5 dBm, respectively. The current consumption is 21 mA under 3.3 V power supply. This mixer shows state-of-the-art noise figure, conversion gain traded-off with 1 dB compression point, and low power consumption.
