A harmonic rejection mixer unit is provided which comprises an input (RF), at least one harmonic rejection unit (HRU) with at least two transistor units (T, T; T, T) for multiplying an input signal from the input (RF) with a multiplication signal (ELO). The harmonic rejection mixer unit furthermore comprises a transistor control signal generating unit (GGU) for generating transistor control signals (GS-GS) for the at least two transistor units (T, T; T, T) of the at least one harmonic rejection unit (HRU) by deriving the transistor control signals (GS-GS) from a local oscillator signal (LO). The transistor control signals (GS, GS) for the at least two transistor units (T, T; T, T) are generated with a duty cycle of &#x3c;50% and are generated such that the shape of the multiplication signal ELO) is achieved by a constructive summation of the output signals from the transistor units (T, T; T, T). The transistor control signals (GS-GS) are generated such that only a summation of output signals from the transistor units with the same sign or with zero is performed.
