Abstract

The disclosure relates to an error-compensated direct digital modulation device, including: a direct digital radio frequency modulator (DDRM), configured to generate a radio frequency (RF) signal based on a modulation of a digital baseband signal; an error estimator configured to determine an error signal resulting from a deviation based on the generated RF signal and a representation of the digital baseband signal; and an error compensator configured to subtract the error signal from the RF signal to provide an error compensated RF signal.
