Abstract
A circuit for signal conditioning including a first stage with a digital/analog converter, a second stage with an I/Q-modulator, and at least one third stage with a mixer. Instead of a multiplicity of independent oscillators, a shared oscillator is provided for the first, second, and third stages, from an output signal of which a respective oscillator signal and clock-pulse signal for each stage of the first, second, and third stages is derived. The oscillator signal and respective clock-pulse signal of the oscillator are supplied via a frequency divider to at least one stage of the first, second, and third stages, or the oscillator signal of the oscillator is supplied via a frequency multiplier to at least one stage. Also, the oscillator signal of the oscillator is supplied as a reference signal to a frequency synthesizer of at least one stage of the first, second, and third stages.
