Patent ID: 7310386

Claim:
A radio receiver comprises: low noise amplifier operably coupled to amplify a modulated radio frequency (RF) signal to produce an amplified modulated RF signal; intermediate frequency (IF) mixing stage operably coupled to mix the amplified modulated RF signal with a local oscillation to produce a modulated IF signal; complex bandpass filter operably coupled to filter the modulated IF signal to produce a filtered IF signal, wherein the filtered IF signal includes information regarding an in-phase component and a quadrature component of the amplified modulated RF signal; an analog to digital converter operably coupled to convert the filtered IF signal into a digital IF signal; first digital mixing module operably coupled to process the digital IF signal with an in-phase digital local oscillation to produce a first baseband signal component; and second digital mixing module operably coupled to process the digital IF signal with a quadrature digital local oscillation to produce a second baseband signal component.
