System and method for time-interpolated power change in a digital pre-distortion circuit

A transmit circuit, comprising:

• an amplifier;
• a digital pre-distortion (DPD) circuit configured to:
• operate with a first DPD coefficient corresponding to a first transmit power level of the amplifier;
• a DPD coefficient management engine configured to:
• in response to a power mode change of the amplifier from the first transmit power level to a second transmit power level, provide a second DPD coefficient corresponding to the second transmit power level;
• a DPD coefficient time-interpolation engine configured to:
• compute a set of time-interpolated DPD coefficients corresponding to a set of time instants for a transient period when the amplifier changes from the first transmit power level to the second transmit power level based on the second DPD coefficient;
• and
• provide, to the DPD circuit, the set of time-interpolated DPD coefficients for operating at the set of time instants during the transient period.
