ABSTRACT:
A radio receiver architecture is disclosed which has first and second front end circuits optimized for reception in two frequency bands. Each front end circuit includes a mixer for downconverting received signals to a respective intermediate frequency. Signals from the two front end circuits are passed to a single analog-to-digital converter. The sampling rate of the analog-to-digital converter and the intermediate frequencies are chosen such that the received signals appear at the same point in different teeth of the alias response of the analog-to-digital converter.
