摘要： An apparatus and method for removing a transmission leakage signal are provided. The apparatus includes: a directional coupler connecting an antenna to a transmission path and a reception path; and a reflection coefficient adjustment unit outputting a reflection signal to the reception path, the reflection signal having the same amplitude as and opposite phase to a first transmission leakage signal generated from the transmission path and input to the reception path and a second transmission leakage signal reflected by the antenna and input to the reception path.

摘要： A transceiver is provided. The transceiver includes a transmission portion which generates a transmission signal; an antenna which transmits the transmission signal and receives a reception signal; a signal division element which receives the transmission signal from the transmission portion and inputs the received transmission signal to the antenna for transmission, and receives the reception signal received by the antenna; an extraction signal adjusting portion which extracts the transmission signal from the signal division element, and adjusts a phase of the extracted signal to generate an output signal; and a receiving portion which receives the reception signal from the signal division element, and applies the output signal from the extraction signal adjusting portion to the reception signal.
