ABSTRACT:
Systems having three coupled transmission lines designed in such a way that any two of which taken together can be used as a differential transmission line with a roughly equal differential mode characteristic impedance while achieving high level of common mode characteristic impedance. The high level of common mode characteristic impedance is achieved by arrangement of the three transmission lines in distinct planes along a transmission axis.
