US Patent 11716152 Transceiver and transceiver calibration method

The application discloses a transceiver, including a calibration signal generation unit, a transmission unit, a receiving unit and a control unit. The calibration signal generation unit generates test signal to the transmission unit in a phase calibration mode. The receiving unit generates a digital receiving signal. The control unit calculates a phase difference between the digital receiving signal and a given reference phase and selectively adjust the transmission unit or the receiving unit accordingly. The application discloses a transceiver calibration method as well.
