An ultra-broadband millimeter wave mixer using 0.18-m CMOS process is presented in this paper.To achieve better operation bandwidth
a uniform distributed topology is utilized for wideband matching.To enhance the conversion gain of the mixer
an IF power combining amplifier is proposed and implemented in this mixer design.The mixer achieves a wide measured conversion gain of -0.2dB4dB from 8 to 40GHz.With the low-pass filter
the mixer exhibits excellent LO-to-IF and RF-to-IF isolation which are both better than 50dB.The DC power consumption of the IF amplifier is less than 32mW.
