Abstract
A device for processing an input signal, including a local oscillator, designed to generate an oscillator signal; a subtracting unit, designed to subtract an amplified correction signal from the input signal in order to generate a corrected input signal; a downmixer, designed to mix the corrected input signal downward to an intermediate frequency using the oscillator signal in order to generate a difference signal; a first amplifier unit, designed to amplify the difference signal in order to generate and output an output signal; a correcting unit, designed to suppress a predefined frequency range of the output signal in order to generate a correction-difference signal; an upmixer, designed to mix the correction-difference signal upward using the oscillator signal in order to generate a correction signal; and a second amplifier unit, designed to amplify the correction signal in order to generate the amplified correction signal.
