Abstract
The invention provides a harmonic direct conversion mixer having a multiplier circuit comprising first and second mixers and a generator for generating two first and two second control signals for controlling the first and second mixers. The control signals are balanced signals and are provided in four phases shifted by π/2 in phase. The frequency of the control signals is different from the frequency of the mixer input signal.
