Abstract
A radio frequency (RF) transmitter including at least one digital signal processing module is described. The at least one digital signal processing module is arranged to receive a complex digital input signal, successively apply pre-distortion to the received complex digital input signal with a progressively finer granularity, simultaneously progressively increase a sampling rate of the received complex digital input signal, and output a first, in-phase digital control word and a second, quadrature, digital control word for controlling at least one digital power amplifier component to generate an RF signal representative of the received complex digital input signal.
