Abstract:
1. A method for gain compensation in a radio frequency (RF) receiver having an RF/intermediate frequency (IF) path including at least one RF/IF analog stage coupled to an RF gain control unit, the at least one RF/IF analog stage including a plurality of components, each of the plurality of components having one or more states, the RF receiver further including an analog-to-digital (A/D) converter, the method comprising the steps of: receiving an RF signal; dynamically adjusting the one or more states of one or more of the plurality of components of the at least one RF/IF analog stage; the A/D converter digitizing the RF signal to derive a digital signal; providing the digital signal to the RF gain control unit; the RF gain control unit generating a gain control signal in response to the digital signal; and dynamically adjusting the digital signal from the A/D converter to compensate for adjusting the one or more states of the one or more of the plurality of components of the at least one RF/IF analog stage in response to the gain control signal and a gain change value associated with the at least one RF/IF analog stage.
