Abstract
Disclosed is an RF transceiver in which transmission and reception are simultaneously performed, wherein a magnitude of a transmission leakage signal mixed into a receiving signal is measured, the maximum and minimum scopes on I/Q vector phase-plane in which an offset vector exists is set using the measured magnitude of the transmission leakage signal, the offset vector offsetting the transmission leakage signal as much as possible, a detection area in which the offset vector exists is determined in the set scope, and the offset vector is detected.
