Abstract
Circuit arrangement for a wideband mixer () with a multiplicative mixing stage () which exhibits a carrier frequency input () for coupling in a differential carrier frequency signal (LOP, LON), a mixing stage input () for coupling in a predistorted differential input signal (LFPD, LFND), and an output () for coupling out a differential output signal (OUTP, OUTN) which is generated from the differential carrier frequency signal (LOP, LON) and the predistorted differential input signal (LFPD, LFND) by multiplicative mixing, the predistorted differential input signal (LFPD, LFND) being generated from a differential input signal (LFP, LFN) by means of a quadratic predistortion and a linear predistortion.
