چکیده
This paper presents the analysis, design and implementation of a millimeter-wave W-band power detector. Fabricated in a 0.18-μm SiGe BiCMOS technology, the detector circuit exhibits a responsivity of 91 kV/W, a noise equivalent power of 0.5 pW/Hz, and a noise figure of 29 dB. The power dissipation of the detector is 75 μW. Reasonable agreement between simulations and measurements is obtained. To the authors’ best knowledge, the detector in this work achieves the highest responsivity reported to date for any solid-state W-band detector. Index Terms — BiCMOS integrated circuits, power detector, passive imaging, millimeter-wave, W-band, Dicke switch, direct-detection, radiometers.

This paper presents two broadband LNAs covering the frequency ranges from 47 to 77 GHz and 73 to 140 GHz, with peak gain above 20 dB. A proposed Ttype matching topology has been adopted in both circuits to achieve the wide bandwidth. While the V-band LNA achieves the design target, the bandwidth in W/F-band is reduced to 73-140 GHz, with a mid-band gain of 20 dB. The measured NF is below 7.2 dB...
