Aspects of a method and system for processing signals in a high performance receive chain may include amplifying a plurality of radio frequency signals in one or more respective one or ones of a plurality of amplifier chains in a multistandard radio frequency front-end, which may comprise one or more shared processing stages. The plurality of radio frequency signals may be compliant with a plurality of radio frequency communication standards and may be received concurrently. The one or more shared processing stages may be shared between two or more of the plurality of amplifier chains. Each of the two or more of the plurality of amplifier chains may be operable to amplify signals compliant with different radio frequency communication standards.

Method and system for processing signals in a high performance receive chain

Aspects of a method and system for processing signals in a high performance receive chain may include amplifying radio frequency signals in amplifier chains in a multistandard radio frequency front-end, comprising one or more shared processing stages, and combining, with substantially equal gain, a number of phase-shifted radio frequency signals of the radio frequency signals into substantially equal-gain-combined radio frequency signals. The substantially equal-gain-combined radio frequency signals may be demodulated to obtain inphase channels and quadrature channels. A number of inphase channels and quadrature channels may be processed in I-channel processing blocks and Q-channel processing blocks to generate an output analog baseband signal. The multistandard radio frequency front-end may be capable of processing Bluetooth&#xae; signals and Wireless Local Area Network (WLAN) signals. The amplifier chains may comprise a first amplifier and a second amplifier, where the first amplifier may be shared between Bluetooth&#xae; signal processing paths and WLAN signal processing paths.
