TRANSMISSION LINE DEVICE, AND ELECTRONIC APPARATUS USING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide a transmission line device capable of increasing density while reducing crosstalk noise. Ž<P>SOLUTION: This transmission line device includes: a first transmission line and a second transmission line for subjecting an input signal to differential transmission; a third transmission line and a fourth transmission line for subjecting an output signal to differential transmission; and a circuit element wherein the first and second transmission lines are electrically connected to input terminals and the third and fourth transmission lines are electrically connected to output terminals. The transmission line device has a structure wherein the second transmission line is arranged to be close to the third transmission line relative to the fourth transmission line; the phase of a signal at the input terminal of the second transmission line is almost equal to that of a signal at the output terminal of the third transmission line; and the phase of a signal at the input terminal of the first transmission line is almost equal to that of a signal at the output terminal of the fourth transmission line.
