Abstract: An active switching frequency mixer having an improved linearity is provided to realize the high linearity by cancelling out a third order intermodulation current component generated in a switching stage and a third order intermodulation current component generated in a transconductance stage, mutually. An active switching frequency mixer having an improved linearity comprises a transconductance stage(110) and a switching stage(120). The transconductance stage has a plurality of active elements, and at least one main signal is inputted to the transconductance stage. The switching stage is coupled with the transconductance stage, and has a plurality of active elements. At least one LO(Local Oscillator) signal is inputted to the switching stage, and at least one IF(Intermediate Frequency) signal is outputted from the switching stage. A resonance inductor(111) is connected to a common source node of at least one active element pair or more among the plurality of active elements in the switching stage.
