Patent ID: 6970681

Claim:
An integrated multi-mode radio receiver comprises: shared front-end operably coupled to receive a radio frequency (RF) signal that is modulated in accordance with one of a plurality of operational modes, wherein the shared front-end converts the RF signal into an I component and a Q component of one of a plurality of intermediate frequency (IF) signals based on a selection signal that is indicative of the one of the plurality of operational modes; first multiplexor operably coupled to provide the I and Q components of the one of the plurality of IF signals to a low pass filter when the selection signal indicates a first mode of operation and to provide the I and Q components of the one of the plurality of IF signals to a band pass filter when the selection signal indicates a second mode of operation; the low pass filter operably coupled to low pass filter the I and Q components to produce low pass filtered I and Q components; the band pass filter operably coupled to band pass filter the I and Q components to produce band pass filtered I and Q components; second multiplexor operably coupled to receive the low pass filtered I and Q components and the band pass filtered I and Q components, wherein the second multiplexor outputs the low pass filtered I and Q components when the selection signal indicates the first mode of operation and outputs the band pass filtered I and Q components when the selection signal indicates the second mode of operation; and amplifying module operably coupled to amplify the low pass filtered I and Q components or the band pass filtered I and Q components to produce amplified I and Q components.
