A digital polar transmitter includes a baseband processor configured to receive an input signal and to convert the input signal into a baseband amplitude component and a baseband phase component. The transmitter also includes a phase modulator in communication with the baseband processor. The phase modulator is configured to modulate an RF carrier signal based on the phase component and to generate a phase-modulated RF carrier signal. A power amplifier is provided in communication with the baseband processor and the phase modulator. The power amplifier is configured to amplify the phase-modulated RF carrier signal based on the baseband amplitude component and to generate an amplified RF signal. The transmitter also includes a digital feedback loop in communication with the power amplifier and the baseband processor. The digital feedback loop is configured to detect the amplified RF signal and to provide a digital amplitude feedback signal and a detected phase feedback signal to the baseband processor.

An apparatus may include a non-linear module, a control module, and a calibration module. The non-linear module produces an output signal from an input signal. The control module selects, upon an occurrence of a calibration condition, a calibration operation from two or more calibration operations. Each of the two or more calibration operations may generate one or more correction values for the non-linear module. Further, each of the calibration operations produces the input signal from a pre-input signal. This selected calibration operation is performed by the calibration module. The two or more calibration operations include a first calibration operation and a second calibration operation. The first calibration operation produces the input signal from the pre-input signal according to a predictive technique. The second calibration operation produces the input signal from the pre-input signal according to a non-predictive technique.
