1. A method for compensating for phase discontinuities on a communication device, comprising:

  • determining a desired output power on a communication device;

    determining, on the communication device, a Digital-to-Analog Converter (DAC) gain corresponding to the desired output power;

    determining, on the communication device, a cumulative phase offset based on the DAC gain or the desired output power;

    applying the DAC gain to the communication device; and

    applying, on the communication device, a phase compensation to a rotator to adjust for the cumulative phase offset.
