Abstract
A transceiving device includes a calibration signal generation unit, a phase adjusting unit, a transmission unit, a receiving unit, and a calibration unit. In a calibration mode, the calibration signal generation unit generates an in-phase (I) test signal and a quadrature (Q) test signal. The phase adjusting unit adjusts the I test signal and the Q test signal to generate an adjusted I test signal and an adjusted Q test signal according to a phase controlling signal. The transmission unit generates a radio frequency (RF) signal according to the adjusted I test signal and the adjusted Q test signal. The receiving unit receives the RF signal so as to generate an I receiving signal and a Q receiving signal. The calibration unit generates the phase controlling signal according to the I test signal, the Q test signal, the I receiving signal, and the Q receiving signal.
