Abstract: A communication system includes a transmitting device configured to transmit data and a receiving device configured to receive the data. The transmitting device includes first and second transmission lines and a differential signal outputter configured to generate differential signals from the microwave signal corresponding to the data, and to output one of the differential signals to the first transmission line and the other differential signal to the second transmission line. The receiving device includes third and fourth transmission lines and a converter. The differential signals are transmitted to the third and fourth transmission lines from the first and second transmission lines via line-to-line couplings. The converter then converts the differential signals into the microwave signal corresponding to the data, and outputs the converted microwave signal.
