HIGH SPEED TRANSMISSION LINE |
摘要 |
A transmission line having substantially reduced far-end forward wave crosstalk is characterized by a single layer of dielectric material having a thickness chosen to provide a forward wave coupling constant KF substantially equal to zero. The dielectric layer is located on a ground plane, and has a plurality of signal carrying conductors embedded in it. The thickness H of the dielectric underlayer below the signal carrying conductors is chosen to provide a transmission line having the selected values of impedance, etc. and substantially reduced forward wave crosstalk. The thickness t of the dielectric overlayer above the signal carrying conductors is chosen (for the selected value of thickness H of the dielectric underlayer) at the finite value critical thickness at which forward wave mutual capacitance and forward wave mutual inductance cancel to a null. The ground plane and the signal carrying conductors can be superconductors. |
