Abstract
A compensating circuit for a mixer stage is provided, wherein the mixer stage has an input stage to which an input signal for mixing can be applied and has, following the input stage, a switching stage for mixing a differential input signal—obtained from the input stage as a function of the input signal—with an oscillator signal, wherein the input of the compensating circuit can be connected to an input signal terminal of the input stage and the output of the compensating circuit can be connected to an input signal terminal of the switching circuit at which the differential input signal obtained by means of the input stage is present, and wherein a compensating signal obtained by means of a compensating stage of the compensating circuit, in particular for compensating intermodulation products, can be produced by the compensating circuit at its output. The compensating circuit has a compensating input stage with means for influencing an amplitude and/or phase of the input signal, by which means the compensating stage can be supplied with a modified input signal.
