Zusammenfassung:A method for increasing an accuracy of a transceiver loopback calibration includes determining a time difference between the use of a local oscillator signal by a second mixing circuit within a receive path of the transceiver and the use of the local oscillator signal by a first mixing circuit within a transmit path of the transceiver. The method further includes delaying the local oscillator signal for the first mixing circuit or for the second mixing circuit to reduce the time difference; and performing a loopback calibration of the transceiver at the reduced time difference.
