Patent ID: 8138817

Claim:
An electronic device comprising; a passive harmonic-rejection mixer with an input for receiving an input signal and an output for supplying a output signal, wherein the mixer comprises multiple segments connected to the input; each respective one of the segments has a respective segment output for supplying a respective contribution to the output signal; the mixer comprises a summing module connected to the respective segment outputs for summing the respective contributions for generating the output signal; each respective segment comprises a respective gating module and a respective amplifier; each respective gating module has a gating input connected to the input for receiving the input signal and a control input to receive a control signal; each respective amplifier has an amplifier input connected to a gating output of the respective gating module; each respective amplifier has an amplifier output connected to the respective segment output; and each respective gating module is operative to selectively pass the input signal, or pass the input signal with inverted polarity, to the gating responsive to the control signal.
