A receiver includes a mixer with a first input, a second input and one output. An input signal (SRF(t)), which has a high frequency component fRF, is applied to the first input, and a local oscillator signal (SLOnew(t)) is applied to the second input of the mixer. The local oscillator signal (SLOnew(t)) is generated by a source and the local oscillator signal (SLOnew(t)) has a frequency component with a frequency fLO. The frequency fLOnew is at least three times lower than the frequency fRF of the input signal (SRF(t)). The mixer down-converts the input signal (SRF(t)) to a lower frequency band.
