Abstract

This paper presents a fully differential low-power 60 GHz Front-End, which comprises a variable gain differential LNA and a low-power Gilbert mixer. The differential LNA features a current folded architecture to save power. Its gain can be tuned from zero to 17.3 dB. It is 15.3 dB for fully differential operation at 10 mW DC power. The measured 3 dB bandwidth extends from 57 to 64 GHz. Both input and output return losses are measured to be below -10 dB in the same frequency range. The mixer core is a Gilbert cell, which draws 1.44 mA from 3.3 V DC supply. Its voltage conversion gain is optimized to be 10 dB. This front-end is best suited for 60 GHz beam steering system where multiple front-ends are required.
