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 3 ± 2 dB measured conversion gain (to 50-Ω load) from 25 to 75 GHz with a compact chip size of 0.30 mm2. The OP1 dB of the mixer is 1 dBm and - 4 dBm at 40 and 60 GHz, respectively. To the best of our knowledge, this monolithic microwave integrated circuit is the highest frequency CMOS Gilbert-cell mixer to date.
