Dynamic gain and phase compensation is provided in a radio frequency (RF)
receiver (106) including at least one switched Low Noise Amplifier (LNA)
(212) coupled to an RF gain control unit (226) providing a gain control
signal to the at least one switched LNA (212) for control thereof. The RF
receiver also includes an analog-to-digital (A/D) converter (222) for
digitizing the RF signal and outputting an N-bit digital signal to the RF
gain control unit (226). The method for gain compensation includes
dynamically adjusting the N-bit digital signal to compensate for the at
least one switched LNA (212) in response to the gain control signal. The
method for phase compensation includes dynamically normalizing the N-bit
digital signal into an M-bit signal range to derive an M-bit digital
signal, where M.ltoreq.N and dynamically phase adjusting the M-bit
digital signal to compensate for the at least one switched LNA (212) in
response to the gain control signal.
