ABSTRACT:
A wideband receiver capable of handling the new extended A and B cellular spectrum is provided. Portions of the band are converted using analog conversion into a frequent between Fs/4 and Fs/2 where Fs is a sampling frequency of an analog-to-digital converter. Other portions of the band are converted such that when they are sampled by the analog-to-digital converter aliasing causes them to lie in the baseband frequencies between zero and Fs/2, and more particularly in baseband frequencies which do not interfere with the other converted bands.
