Abstract
A radio frequency, RF, transmitter, comprises a digitally controlled oscillator, DCO, configured to generate an RF signal; and digital modulation circuitry connected to the DCO for modulation of the RF signal, and driven by an RF clock signal derived from the RF signal, wherein the digital modulation circuitry comprises a module configured to apply a compensation for modulation jitter due to the modulation circuitry being driven by the RF clock signal and a compensation for DCO non-linearity.
