Patent ID: 7676206

Claim:
A radio receiver front-end comprises: a tunable antenna interface operably coupled to filter a wide bandwidth signal to produce a filtered wide bandwidth signal in accordance with a band pass region, wherein the wide bandwidth signal includes a plurality of channel signals, wherein the tunable antenna interface is tuned such that the band pass region includes a selected one of the plurality of channel signals, and wherein the band pass region is narrower than the wide bandwidth signal; and a low noise amplifying section operably coupled to amplify the filtered wide bandwidth signal to produce a filtered and amplified wide bandwidth signal, the low noise amplifying section further comprising offset correction and gain control circuits wherein the low noise amplifying section comprises: a first low noise amplifier operably coupled to amplify the filtered wide bandwidth signal based on a first gain setting to produce a first filtered and amplified wide bandwidth signal; a second low noise amplifier operably coupled to amplify the first filtered and amplified wide bandwidth signal based on a second gain setting to produce the filtered and amplified wide bandwidth signal; a feedback network operably coupled to the first and second low noise amplifiers to substantially cancel a DC (direct current) offset of the low noise amplifier section; and a gain control module operably coupled to produce the first and second gain settings based on at least one property corresponding to processing the filtered wide bandwidth signal.
