Abstract
A polar modulator for generating a polar-modulated signal based on amplitude information and phase information includes a phase-locked loop which is implemented to enable a setting of a frequency depending on a control value to obtain a phase-locked loop output signal. The polar modulator further includes a modulation means which is implemented to combine an amplitude modulation signal derived from the amplitude information with the phase-locked loop output signal to generate the polar-modulated signal. The polar modulator further includes a control value generator which is implemented to high-pass filter an amplitude signal derived from the amplitude information, to obtain a high-pass filtered amplitude signal, wherein the control value generator is implemented to combine the high-pass filtered amplitude signal with a phase signal based on the phase information to generate the control value signal representing the control value.
