Abstract
Digital spur reduction in which spurs are kept outside selected channels of interest, with illustrative embodiments relating to an integrated radiofrequency transceiver circuit having digital and analogue components, the circuit having a radiofrequency signal receiver with a local oscillator signal generator configured to provide a local oscillator signal at a frequency fand a mixer configured to combine an input radiofrequency signal with the local oscillator signal to produce an intermediate frequency signal; and a clock signal generator configured to generate a digital clock signal at a frequency ffor operation of the digital components, where the local oscillator signal and/or a reference signal from which the local oscillator signal is derived are generated such that digital spurs lie outside a band selected by the receiver.
