Abstract
Methods and circuits can down convert at least a first RF signal on a first path in a first frequency band to provide a first IF signal. A second RF signal on second path in a second frequency band can be down converted to provide a second IF signal. The first IF signal and the second IF signal are interspersed in the frequency domain, and the first frequency band is different from the second frequency band. A combiner can combine at least part of the first IF signal and the second IF signal to provide a combined signal on an output signal path for reception by a digital processing circuit. The first IF signal or second IF signal can be a Zero IF (ZIF), very low IF (VLIF), or Low IF (LIF) signal.
