Abstract: An apparatus, for automatically selecting a compensation value usable to reduce a second order intermodulation (IM2) product in an output signal of a mixer, may include: a mixer to output a mixed signal; a detector to detect an product in samples corresponding to the mixed signal; a compensation determination circuit to do the following automatically, to apply a plurality of candidate values of a mixer-control signal to the mixer, the mixer-control signal affecting a magnitude of an IM2 product in the mixed signal, to evaluate samples from the detector corresponding to the plurality, respectively, and to select one among the plurality candidate values as the compensation value.
