In a diode mixer circuit MIX, a driving circuit DRIV produces a first, second, third and fourth drive signal DS1, DS2, DS3, DS4. Each drive signal is a combination of a first and a second input signal LO, RF with the following signs:DS1: +LO+RFDS2: +LO-RFDS3: -LO+RFDS4: -LO-RFA first, second, third and fourth diode D1, D2, D3, D4 transfer the first, second, third and fourth drive signal DS1, DS2, DS3, DS4 respectively, to an output O1. The first and fourth diodes D1, D4 have the same polarity relative to the output. The second and third diodes D2, D3 also have the same polarity relative to the output, but opposite to that of the first and fourth diodes D1, D4.A mixer circuit of this type is suitable for a relatively large variety of applications, notably because it may be realized in the form of an integrated circuit.
