Flip-chip assembled 60GHz CMOS receiver front-end

This paper presents an flip-chip assembled 60GHz CMOS receiver front-end. The receiver front-end consists of a cascode LNA, a balun, a harmonic mixer, and an IF amplifier fabricated by 90nm CMOS. The flip-chip assembled cascode LNA performs 31.1dB gain as well as on-wafer probing with NF of 5.8dB and output P
_1dB
of -3.9dBm at 60GHz while consuming 26.9mW. The flip-chip assembled receiver front-end performs 21.3dB of conversion gain.
