TRANSMISSION LINE MEMBER AND ELECTRONIC APPARATUS

摘要

A transmission line member includes a dielectric base body. At an intermediate point in a thickness direction of the dielectric base body, first and second signal conductors are disposed. A reference ground conductor is disposed at one side of the first and second signal conductors in the thickness direction, and an auxiliary ground conductor is disposed at the other side. At intermediate points of the first signal conductor, a coil conductor and a capacitor-defining plate conductor are disposed. The capacitor-defining plate conductor faces the reference ground conductor and the auxiliary ground conductor to connect a low pass filter and the first transmission line. A coil conductor is disposed between the second signal conductor and the reference ground conductor, and connected to the second signal conductor and the reference ground conductor to connect a high pass filter and the second transmission line.
