Abstract
A multi-channel quadrature bandpass-sampling receiver is provided with a plurality of RF signals that are modulated at different carrier frequencies, are frequency-shifted, and are staggered to a first IF frequency. A quadrature bandpass-sampling analog-to-digital demodulator digitizes and down-converts the aggregate RF signals to a second low IF frequency, wherein each frequency-shifted RF signal can be demodulated to DC by a digital down converter.
