Abstract
An apparatus for handling a received signal comprises a reception device, a mixer unit and a compensating unit. The reception unit can receive a received signal. The received signal has at least one signal component at a first frequency. Furthermore, the mixer unit can combine the received signal and a compensating signal using at least one active element in order to obtain a compensated received signal. In addition, the mixer unit can produce a mixer output signal on the basis of the compensated received signal and a local oscillator signal. In this case, the mixer output signal has a signal component, corresponding to the at least one signal component of the received signal, at a second frequency. The first frequency is higher than the second frequency. Furthermore, the compensating unit can produce the compensating signal on the basis of an analysis of the mixer output signal, as a result of which it is possible for noise components that the mixer output signal contains to be reduced on the basis of the compensating signal.
