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.RTM. 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.RTM.
signal processing paths and WLAN signal processing paths.
