    Abstract: A multi-band receiver for receiving an input signal having a frequency situated either in a first band or in a second band. The receiver comprising a mixer for combining an amplified signal having substantially the same frequency as the input signal with a periodical signal generated by a local oscillator. The mixer generates an intermediate frequency signal, the intermediate frequency signal (IF) being inputted to an IF band-pass filter. A central frequency of the band-pass filter is substantially equal to a frequency of the intermediate frequency signal. The receiver is characterized in that the central frequency of the IF band-pass filter is substantially independent of a combining mode of the amplified signal and the periodical signal, the combining mode being selected from an upper heterodyning mode and a lower heterodyning mode.
