    • A coupler improving leakage isolation performance using an adaptive algorithm for preventing the leakage of transmission signal of a transmitter is provided to maximize the isolation effect of the signal leaked from a transmitter to a receiver by adaptively diversifying the characteristic of the coupler between a transceiver and an antenna. An antenna(110) transceives RF(Radio Frequency) signals. A receiver(130) converts radio frequency signals into baseband signals. A transmission unit(120) converts baseband signals into radio frequency signals. A coupler transmits the received RF signals to the receiver. The coupler delivers the transformed radio frequency signals to the antenna. A passive element unit comprises one or more variable passive devices. A controller estimates the intensity of the signal leaked from the receiver among the transformed radio frequency signals. The controller minimizes the signal intensity.

The LDO serves as the power source and voltage regulator of the power amplifier. The modulation of the output signal, in which a size is modulated through the power amplifier, is formed to be identical to the modulation of a baseband signal. The accuracy of a final outputted signal is determined according to the linear dynamic area of the switching power amplifier.
