PROBLEM TO BE SOLVED: To obtain a low voltage mixer circuit which can be integrated to a UWB signal transmission device. SOLUTION: The source of a first pair of the transistors M5, M6 is connected to the output of a first MOS transistor reverser arrangement M1, M3 of a transconductance stage, and the source of the transistors M7, M8 of a second pair is connected to the output of the second MOS transistor reverser arrangement M2, M4 of the transconductance stage. The gate of the first NMOS transistors M5, M8 of differential pairs receives a first carrier frequency signal LOP, and the gate of the second NMOS transistors M6, M7 of the differential pairs receives a second carrier frequency signal LON. A first data signal IN0 is supplied to the input of the first reverser arrangement M1, M3, and a second data signal IN1 is supplied to the input of the second reverser arrangement M2, M4.
