摘要： A receiver is protected by reducing a transmit leakage signal leaked when a transmit signal is radiated through the antenna by using three circulators (transmitter, antenna, and receiver). The transmitter and antenna circulators output the transmit leakage signal to be reduced to less than the transmit signal through a first leakage path. The transmitter and receiver circulators output the transmit leakage signal through a third leakage path and reduce the signal. The transmit leakage signals received through the first and third leakage paths are canceled, and that received through a second leakage path is output to a receiver. The transmit leakage signal has a 40 dB signal reduction compared to the transmit signal, and is transmitted to the receiver.
