CMOS I/Q subharmonic mixer for millimeter-wave atmospheric remote sensing
IEEE Microwave and wireless components letters, 2016•ieeexplore.ieee.org
A compact second harmonic 180 GHz I/Q balanced resistive mixer is realized in a 32-nm
SOI CMOS technology for atmospheric remote sensing applications. The MMIC further
includes two on-chip IF amplifiers at the mixer's I and Q channels. A conversion gain of+ 8
dB is achieved with 74 mW of dc power consumption using a 1.2 V supply. The measured IF
frequency range is from 1 to 10 GHz. The mixer achieves a 20 dB imagerejection (IR) ratio
with an LO input power of+ 4 dBm. The chip size is 0.75 mm 2 including probing pads.
