Title:
AMPLITUDE AND PHASE ALIGNMENT OF PHASED ARRAY ELEMENTS
Document Type and Number:
WIPO Patent Application WO/2024/061090
Kind Code:
A1
Abstract:
Systems and methods for operating a beamforming circuit are described. A processor can activate a transmitting element among a plurality of transmitting elements of a beamforming circuit. The processor can activate a receiving element among a plurality of receiving elements of a beamforming circuit. The processor can receive a direct current (DC) signal that represents phase and amplitude of the activated transmitting element and the activated receiving element. The processor can adjust a setting of the beamforming circuit to receive additional DC signals that represent phases and amplitudes of the activated transmitting element and the activated receiving element under the adjusted setting. The processor can determine calibration values for the beamforming circuit based on the DC signal and the additional DC signals.
