摘要

This paper presents the design and characterization of two broadband millimeter-wave LNAs realized in 0.25- $mu hbox{m}$ and 0.13- $mu hbox{m}$ SiGe BiCMOS technologies. Both circuits adopt a T-type matching topology to achieve the wide bandwidth (47–77 GHz for the $V$ -band LNA and 70–140 GHz for the $W/F$-band LNA). The measured maximum gain is about 23 dB for both LNAs. The measured noise figure (NF) is below 7.2 dB (from 50 to 75 GHz) for the $V$ -band LNA and below 7 dB (from 78 to 110 GHz) for the $W/F$-band LNA. Both LNAs are differential circuits and consume 52/54 mW dc power. To the best of the authors' knowledge, both LNAs achieve the widest bandwidth in corresponding frequency bands with very competitive gain and NF.
