    Abstract: An integrated circuit (IC) device includes an IC die on a substrate, and the substrate includes a group of conductive lines between a high-permittivity dielectric layer and a low-permittivity dielectric layer, with a ground plane separated from the conductive lines by either the high- or low-permittivity dielectric layer. The substrate may include other low-permittivity dielectric layers. The substrate may include other groups of conductive lines between ground planes. The high-permittivity dielectric layer may be within a low-permittivity dielectric core layer.

    Abstract: A filter that can make a reflection delay of an initial stage coupling part correspond to a change in a passband due to a manufacturing error of a substrate or the like is realized. A filter according to an example embodiment includes: a substrate having a dielectric property; an initial stage coupling part formed on the substrate; and an interstage coupling part formed on the substrate. The initial stage coupling part is formed so that a reflection delay is decreased in accordance with an increase in a passband due to a manufacturing error of the substrate or the interstage coupling part, or so that the reflection delay is increased in accordance with a decrease in the passband.

    Abstract: A system for preventing crosstalk between adjacent channels comprises a crossover connector positioned along a length of one channel such that a portion of a positive trace for a first channel is positioned adjacent to a positive trace of a positive trace of an adjacent channel. The position of the crossover connector is based on preventing crosstalk and crossover connectors on adjacent channels may be staggered to further prevent crosstalk. A crossover connector may be based on capacitors or resistors to prevent crosstalk.
