Zusammenfassung:A method and device for calibrating a DC offset and an I-Q imbalance component of an RF transceiver, the method including inputting a test signal into a transmitter, and converting the test signal into an analogue test signal; converting the analogue test signal using a transmitting mixer; sub-sampling a signal output from the transmitting mixer; and computing a DC offset calibrating constant number and an I-Q imbalance calibrating constant number from a sub-sampled signal.
