The invention relates to a mixer circuit 31 comprising a down-conversion
mixing component 33 arranged for down-converting an input radio frequency
signal Irf+, Irf-. In order to improve such a mixer circuit, it is
proposed that it comprises in addition an active mixer load circuit 34
connected to output terminals of the mixing component. The active mixer
load circuit includes an active mixer load 51, T1, T2 and modulating
means S1-S4 arranged for modulating a flicker noise produced by the
active mixer load away from the signal band of a signal Ibb+, Ibb- output
by the down-conversion mixing component. The invention relates equally to
a receiver, a chip and a device comprising such a mixer circuit and to a
method for use with such a mixer circuit.
