PURPOSE: A ubiquitous wireless transmission and reception device and a method thereof are provided to efficiently remove the transmission leakage signal. CONSTITUTION: An attenuator(145) attenuates a coupling transmission signal converted into an inverse phase to correspond to the power of a transmission leakage signal, and outputs a mirror transmission leakage signal. A coupling unit(150) is connected to a third terminal, and combines the transmission leakage signal with the mirror transmission leakage signal. The combination unit removes the transmission leakage signal through offset, and outputs the reception signal to a reception terminal. |
