Aspects of the disclosure provide a transmitter that includes a pre-distortion module and a phase controller. The pre-distortion module is configured to receive a first digital value and generate a first pre-distorted digital value based on the first digital value and a corresponding angle. The first digital value is a combination of an in-phase component and a quadrature component of a signal for transmission. The phase controller is configured to control an amplifier to drive a current according to the first pre-distorted digital value and phase information in relation to the first digital value during a first phase range of a carrier signal determined at least partially based on the angle. |
