Abstract
A mixer arrangement includes a mixer cell coupled by a signal input to a mixer input, and is embodied for frequency conversion of a signal present on the input side to an intermediate frequency. A first current source is coupled to the signal input of the mixer cell, and a second current source is coupled to a signal output of the mixer cell. The mixer arrangement furthermore includes a sensor circuit embodied for detection and for outputting of a value which is derived from a current of one of the current sources. A desired value regulating circuit is coupled by a feedback input to the sensor circuit and is designed for outputting a regulating signal to the one current source derived from a comparison of a signal present at a feedback input with a desired value.
