60 GHz double-balanced up-conversion mixer on 130 nm CMOS technology

Abstract

A millimetre-wave Gilbert-cell up-conversion mixer using standard 130nm CMOS technology is presented. This mixer has a power conversion gain of better than 2dB and has the highest reported OP1dB of -5.6dBm when driven with a LO power of 0dBm. The LO to RF isolation are better than 37dB for LO from 57 to 65GHz. Microstrip lines were employed for the matching network design at the mixer output. This is believed to be the first CMOS Gilbert-cell up-conversion mixer operating in the 60GHz frequency band using fundamental LO. © The Institution of Engineering and Technology 2008.
