Abstract

Mixer circuits (1) comprise mixers (2) for receiving input signals and oscillation signals and for outputting output signals. By providing the mixers (2) with loads (3) having adjustable load values and by introducing adjustors (4) for adjusting and sweeping the loads (3), which adjusted loads (3) have different load values at different moments in time, and by introducing detectors (5) for detecting components such as second order intermodulation products of the output signal per load value and selectors (6) for selecting detection results and for instructing the adjustors (4) to set the loads (3) in response to the selected detection result, the mixer (2) is calibrated. The detectors (5) comprise filtering circuitry (52) for filtering the components and comprising slope detection circuitry (53) and the selectors (6) comprise comparison circuitry (61) for comparing slope values with each other for finding an extreme slope value that defines the detection result to be selected. The input signals comprise amplitude modulation jammer signals or two tones signals.
