An analog to digital converter device including: an input to receive a radio frequency (RF) signal; a plurality of delay elements coupled in series to the input, wherein each element has an output configured to provide the RF signal with a temporal delay corresponding to a different number of the delay elements; a sample rate reduction system having a plurality of inputs each being coupled to a corresponding one of the delay element outputs, and configured to sample the delayed RF signals and provide M-sample outputs, each of the M-sample outputs being sampled at a reduced sampling rate equal to the sampling rate divided by M, M being an integer sample rate reduction value; and an Norder complex bandpass filter coupled to the sample rate reduction system, the complex bandpass filter being configured to filter each of the M-sample outputs to obtain a plurality of complex baseband signals.
