Abstract:
    A bandpass sampling receiver is proposed for receiving RF signals, comprising: the first ADC, for converting the RF signal into the first path of digital signal under the control of the first sampling clock signal; the second ADC, for converting the RF signal into the second path of digital signal under the control of the second sampling clock signal; a signal separating unit, for separating the in-phase signal and the quadrature signal in the first path of digital signal and the second path of digital signal; wherein the frequency of said first sampling clock signal and said second sampling clock signal is 1/N of that of said RF signal, and N is a natural number.
