US Patent 11411309 Local oscillator spur suppression in a phased array system

A system comprises local oscillator spur suppression circuitry, local oscillator generator circuitry), and beamforming circuitry. The local oscillator spur suppression circuitry is operable to generate a phase adjustment value. The local oscillator generator circuitry is operable to generate a local oscillator signal at a determined phase equal to a reference phase offset by the phase adjustment value. The beamforming circuitry is operable to receive the phase adjustment value, and generate a beamforming coefficient to be applied to a signal that is to be upconverted by the local oscillator signal and transmitted via an antenna element of a phased array, wherein the generation of the beamforming coefficient is based on the phase adjustment value and a location of the antenna element within the phased array.
