    A compact and broadband 25-75-GHz fully integrated double-balance Gilbert-cell mixer using 90-nm standard mixed-signal/radio frequency (RF) CMOS technology is presented in this letter. A broadband matching network, LC ladder, for Gilbert-cell mixer transconductance stage design is introduced to achieve the flatness of conversion gain and good RF port impedance match over broad bandwidth. This Gilbert-cell mixer exhibits 3plusmn2dB measured conversion gain (to 50-Omega load) from 25 to 75GHz with a compact chip size of 0.30mm2. The OP1 dB of the mixer is 1dBm and -4dBm at 40 and 60GHz, respectively. To the best of our knowledge, this monolithic microwave integrated circuit is the highest frequency CMOS Gilbert-cell mixer to date

    Design and analysis of a 0.8-77.5-GHz ultra-broadband distributed drain mixer using 0.13-μm CMOS technology
    (IEEE Microwave Theory and Techniques Society, 2009-03-01) Hong-Yuan Yang; Jeng-Han Tsai; Chi-Hsueh Wang; Chin-Shen Lin; Wei-Heng Lin; Kun-You Lin; Tian-Wei Huang; Huei Wang
    A compact and broadband 0.8-77.5-GHz passive distributed drain mixer using standard 0.13-mum CMOS technology is presented in this paper. To extend the operation bandwidth, a uniform distributed topology is utilized for wideband matching. This paper also analyzes the device size and number of stages for the bandwidth of the CMOS distributed drain mixer. To optimize the conversion gain performance of the CMOS drain mixer, a gate bias optimization method is proposed and successfully implemented in the mixer design. This mixer consumes zero dc power and exhibits a measured conversion loss of 5.5 plusmn1 dB from 0.8 to 77.5 GHz with a compact size of 0.67 0.58 mm2 . The output 1-dB compression point is -8.5 dBm at 20 GHz. To best of our knowledge, this monolithic microwave integrated circuit has the widest operation bandwidth among CMOS wideband mixers to date with good conversion efficiency and zero dc power consumption.
