Abstract
The present disclosure relates to a method for reducing second order intermodulation distortion in a harmonic rejection mixer arranged for down-converting a radio frequency signal to an in-phase and a quadrature baseband signal. The method includes adjusting an output current of a first mixer, to reduce the second order intermodulation distortion in the quadrature baseband signal to a first value, and adjusting an output current of a second mixer, to reduce the second order intermodulation distortion in the in-phase baseband signal to a second value.
