摘要:
A system includes a transmitter to drive a transmission signal via a first and second transmission line. One half of the transmission signal is applied to the first transmission line and the other half of the transmission signal is applied to the second transmission line. An antenna radiates the transmission signal from the transmitter and receives a reception signal. The reception signal is driven in the opposite direction of the transmission signal on the first and second transmission lines. A plurality of differential amplifiers receive the reception signal from different sections of the first and second transmission lines and generate amplified output signals to a receiver output path having a first and second receiver transmission line. The differential amplifiers reject the one half of the transmission signal applied to the first transmission line and the other half of the transmission signal applied to the second transmission line.
