【24h】 EMC Design Practices: The Illusive RF Radiated Coupling Loop: Part 2 in a Series

机译EMC设计实践:虚幻的RF辐射耦合环路:系列的第2部分

【摘要】Let' s hear it for the lowly wire. That mysterious device that can be a conductor, a resistor, a capacitor plate, an inductor, and an antenna all packaged in one exciting component. Soft and flexible, thick or thin, narrow or wide, rigid and stiff, a great conductor—or maybe not. All these terms describe a component with really unique properties that is largely ignored by electronics designers. Most of the time, wire routing creates loops that provide paths for signal currents to move from a source to a load and return back to the source. Loops appear in ICs where they interconnect millions of transistors, on PCBs and backplanes where the trace loops are larger but fewer, and in cables where loop areas can be extremely large.
