US Patent 11316500 Beamforming with phase correction
Article
A transmitter apparatus that performs beamforming with phase correction uses power detectors present between power amplifiers (PAs) and antennas are used to measure power amplitudes on at least two transmission paths. The sum and difference of these amplitudes are then evaluated to determine a phase difference therebetween. A phase of one signal contributing to the sum and difference may be modified until the sum and difference are the same. Based on an amount of phase modification, a correction signal may be sent to a beamforming circuit to provide phase correction during beamforming.
