A mixer circuit arrangement for frequency - changing an RF input signal to an IF signal comprises an input stage, a filter stage, and a mixer stage. The input stage supplies differential current signals to the filter stage, which attenuates image signals and preferably also local oscillator signals. The mixer stage mixes the filtered differential current signals with the local oscillator signal to provide the IF signal.
