Original Abstract Submitted
devices are disclosed that include a wideband millimeter wave (mmw) via transition design for multilayer printed circuit boards (mlbs). in various instances embodiments, a via is dimensioned to provide impedance matching to stripline tracing connected at the end of the via. impedance matching in the via may eliminate the need for an impedance matching section on the stripline tracing. in some instances, the dimensions of the via pad diameter and the via keepout diameter are selected to tune a via transition structure to selected frequencies and/or frequency bandwidths.
