Abstract:
1. A method for integrating control of power and predistortion in a radio-frequency (RF) amplifier, the method comprising: retrieving a set of gain and attenuator settings from an automatic gain control (AGC) database that contains a different set of gain and attenuator settings for each transmission type; retrieving a set of predistortion parameters from a predistortion database that contains a different set of parameters for each transmission type; applying the attenuator setting to attenuators associated with the amplifier; combining the gain setting with the predistortion parameters to obtain a composite complex gain correction; applying the composite complex gain correction to amplifier input signals, to effect predistortion and amplifier gain control; continually updating the AGC database to reflect changes in amplifier performance due to aging and environmental conditions; and continually updating the predistortion database to reflect changes in amplifier performance due to aging and environmental conditions.
