A mixer stage is provided that mixes a differential input signal with a differential square-wave signal of an oscillator, having a first amplifier element and a second amplifier element, each of which amplifier elements has a first current connection, a second current connection, and a connection for the differential input signal, having four control elements and also a first output and a second output, wherein the four control elements are modulated in pairs by the differential square-wave signal, thereby connecting each second current connection alternately, and in each case individually, to one of the two outputs. The mixer stage has field-effect transistors as amplifier elements whose first current connections are connected to a constant reference voltage. In addition, a method for mixing frequencies that uses this mixer stage is also disclosed.
