    摘要: According to some embodiments, an up-conversion mixer includes a mixer cell having an output node arranged to provide an output. An input stage is coupled to the mixer cell and arranged to receive an input signal. The mixer cell is configured to generate the output with an up-converted frequency compared to an input frequency of the input signal. The input stage is configured to reduce a third order harmonic term of the output so that an output power plot of the third order harmonic term with respect to an input power has a notch with a local minimum.
