When the line center spacing is not less than 3 times the line width, most of the electric fields can be kept from interfering with each other. This is the 3W rule. The 3W principle means that when multiple high-speed signal …

Web3W规则表示使用半径大于3倍线宽W的圆弧进行拐弯，能使得转弯处线宽变化较小，从而减小不连续性，在微带线上称之为“扫掠弯头”，如图5所示。 图5 扫掠弯头示意图 对该结构进行电磁仿真，仿真结果如图6所示。 当扫掠弯头半径R=3W时，S11=-34.6dB，当R=4W时，S11反而增加，直到R=11W时，扫掠弯头的S11才能降到很低，达到-40.03dB。 此时就可以解 … http://etimes.twce.org.tw/%E6%96%BD%E5%B7%A5%E6%8A%80%E8%A1%93/2535-%E8%AB%87%E9%8B%BC%E6%89%BF%E9%88%91%E4%BD%BF%E7%94%A8%E7%9A%84%E8%B7%A8%E5%BA%A6%E5%95%8F%E9%A1%8C.html merry music christmas dean martin
