Abstract:
1. A differential signal transmission cable structure for transmitting differential signals having a GHz frequency band, comprising: a differential signal transmission pair cable connecting a driver circuit and a receiver circuit that transmits the differential signals having a GHz frequency band while matching characteristic impedances of the driver circuit and the receiver circuit; and a power supply ground transmission pair cable connecting a first power supply and ground connected to the driver circuit and a second power supply and ground connected to the receiver circuit that matches characteristic impedances of the first power supply and ground and the second power supply and ground; wherein, as matching characteristic impedances of the power supply ground transmission cable and the differential signal transmission cable, TEM waves of the differential signals having a GHz frequency band are maintained when the differential signal transmission cable transmits the transmission signals having a GHz frequency band.
