A fully integrated 60 GHz LNA in SiGe:C BiCMOS technology

This paper presents a SiGe differential low-noise amplifier (LNA) for the V-band. The measured gain at 60 GHz is 18 dB, and the input return loss is below -15 dB. The 3-dB bandwidth is from 49 GHz to 71 GHz. Measured and simulated S-parameters agree well over the whole range. The LNA draws 30 mA from a 2.2 V supply. It facilitates the design of a fully integrated WLAN receiver in the 57-64 GHz band.
