1. A transmitter comprising:
a pre-distortion module configured to (i) receive a first digital value, and generate a first pre-distorted digital value based on the first digital value and a corresponding distortion angle, the first digital value being a first combination of an in-phase component and a quadrature component of a signal for transmission, and (ii) receive a second digital value, and generate a second pre-distorted digital value based on the second digital value and the corresponding distortion angle, the second digital value being a second combination of the in-phase component and the quadrature component of the signal for transmission; and a phase controller, coupled to the pre-distortion module and an amplifier, configured to (a) control the 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 corresponding distortion angle, and (b) control the amplifier to drive the current according to the second pre-distorted digital value and phase information in relation to the second digital value, during a second phase range of the carrier signal determined at least partially based on the corresponding distortion angle. |
