Abstract: A method for determining a signal propagation time mismatch in a modulator comprises generating a predetermined signal shape of a amplitude component of a radio frequency signal generating one or more predetermined conditions in a frequency component of the radio frequency signal at a first time interval relative to the predetermined signal shape and detecting the one or more predetermined conditions in the frequency component at a second time interval. The method further includes determining the amplitude component at the second time interval and calculating a signal propagation time mismatch value based on the signal shape of the amplitude component, on the first time interval and the second time interval.

Abstract: A transmitter for generating an analog radio frequency transmit signal is provided. The transmitter includes a digital-to-analog converter configured to receive an oscillation signal and a first digital data signal to generate an analog radio frequency transmit signal. Further, the transmitter includes an oscillation signal generator configured to generate the oscillation signal with an oscillation frequency based on a second digital data signal. The transmitter additionally includes a controller configured to change a first sample frequency of the first digital data signal from a first frequency to a value different than the oscillation frequency, wherein the first frequency is at least the oscillation frequency.
