Crosstalk reduction in a crosspoint thyristor switching array using a shielded dielectric stack

摘要

A method and apparatus are disclosed for reducing crosstalk and dispersion in a crosspoint monolithic microwave integrated circuit (MMIC) switch array operating in a range between DC and microwave frequencies. In accordance with an exemplary embodiment, the crosspoint MMIC switch array includes a dielectric stack, a substrate, a first ground plane, a plurality of thyristor switches, a plurality of signal transmission lines arranged in rows; and a plurality of signal transmission lines arranged in columns. The plurality of signal transmission lines arranged in columns intersect the plurality of signal transmission lines arranged in rows at a plurality of intersection points. Each of the plurality of thyristor switches is associated with one of the plurality of intersection points. Each of the plurality of thyristor switches is in electrical contact with the signal transmission lines that intersect at the associated intersection point.
