  • Circuit configuration for mixing an input signal and an oscillator signal with one another
    Patent number: 6456144
    Abstract: The circuit configuration mixes an input signal with an oscillator signal. A phase splitter with one input and two voltage outputs receives the oscillator signal and carries at its outputs orthogonal oscillator signals, which are phase-shifted through 90° with respect to one another. A first differential amplifier has a voltage input connected to one of the two voltage outputs of the phase splitter. A second differential amplifier has a voltage input connected to the other of the two voltage outputs of the phase splitter and one current output. A first current source controlled by the input signal supplies the first differential amplifier. A second current source that is controlled by the input signal supplies the second differential amplifier. A first phase shifter is connected downstream of the first differential amplifier, and a second phase shifter is connected downstream of the second differential amplifier.
