Abstract
An electronic filtering device includes continuous trace on a dielectric substrate and a dissipation layer communicatively coupled to the trace. The dissipation layer may include disconnected metal particles, which may be embedded in a substrate, for example in an epoxy. The continuous trace may be meandering, for example crenulated, coil or spiral signal path. At least a second continuous trace may be spaced from the first by the substrate, and conductively coupled by a via. The electronic filtering device may be used in one or more printed circuit boards (PCBs) that form stages of an input/output system.
Claims17
An electrical signal filtering device comprising:
- a dielectric medium;
- a first continuous conductive path carried by the dielectric medium that forms a first circuitous route for connecting a first pair of points on the dielectric medium, the first continuous conductive path comprising a first conductive layer formed of a conductive metal having a first resistance and a first dissipative layer formed of a conductive metal having a second resistance that is higher than the first resistance, the first conductive layer and the first dissipative layer plated one on top of the other such that the first conductive layer provides a path through which an electrical signal flows and the first dissipative layer provides dissipation of unwanted signal frequencies;
- and
- a second continuous conductive path that establishes a second circuitous route for connecting a second pair of points, the second continuous conductive path spaced from the first continuous conductive path by at least a portion of the dielectric medium, wherein the first continuous conductive path is galvanically coupled to the second continuous conductive path by a via connection extending through at least a portion of the dielectric medium.
