Abstract:
1. A wireless receiver for multiple frequency bands reception comprising: a single receive radio frequency (RF) circuit having an RF bandpass substantially confined to encompass at least two non-overlapped such frequency bands at RF; a single in-phase and quadrature (approximately I, Q) pair of intermediate frequency (IF) sections having an IF passband; and a mixer circuit including an in-phase and quadrature (I,Q) pair of mixers fed by said RF circuit and having a local oscillator with in-phase and quadrature outputs coupled to said mixers respectively, said mixer circuit operable to inject and substantially overlap the at least two non-overlapped frequency bands with each other into the IQ IF sections in the IF passband, the IF passband substantially confined to a bandwidth encompassing the thereby-overlapped frequency bands.
