A K-band Up-conversion Mixer in 65nm CMOS

Abstract

This paper presents a K-band up-conversion mixer, which consists of an active Gilbert mixer cell and a radio frequency (RF) buffer. Fabricated in a 65nm CMOS technology, the up-conversion mixer achieves a conversion gain (CG) of 12.8 dB, an output 1-dB compression point (OP1dB) of 2.5 dBm and a third-order output intercept point (OIP3) of 14.7 dBm, while depleting a 31-mW DC power dissipation at a 1.2-V supply voltage.
