  • Radio frequency circuits and methods of processing radio frequency signals
    Patent number: 11177846
    Abstract: A radio frequency circuit for processing a radio frequency signal. The circuit comprises a variable frequency oscillator system and a radio frequency signal processing circuit arranged to process a radio frequency signal using the output of the variable frequency oscillator system. A digitiser is arranged to receive the output of the radio frequency signal processing circuit and generate a digitised signal. A phase noise capture circuit is arranged to capture the phase noise in the output of the variable frequency oscillator system. The radio frequency circuit is arranged to compensate for the effect of the phase noise in the output of the variable frequency oscillator system on the output of the radio frequency signal processing circuit, by digitally processing the digitised signal generated by the digitiser using the output of the phase noise capture circuit.
