我做的线材却是在低频M1、中频M2、M3段稍底出一点点,如何改善这个问题点?
就底了2个DB!

导体的绞距减小一点,铜线用上公差。

铝箔缠绕过紧也可能。

包帶很松的,是一根cu的!

能不能把整份报告附上...
需要看图形.

skew倒是做的很好啊,呵呵

結構有沒有分析過?如有報告請上傳看看

如何把图片上传到论坛上,又不需要GB下载!
能告诉我吗?

把IMP提高几欧姆。

提高阻抗!

目前已經提高阻抗了 ,我把p=40時有一點m3下掉。謝謝大家的討論!

我將把設定的 p減低,m3就通過了 ,但問題又來,低頻時出現沾邊;許多人說我包帶有問題,但我通過分析電線,素線\p\包帶(包帶就像高速公路一樣平坦)等ok.
今晚一定把它搞定。

怎麼 沒有人參加討論呢?
加大p會不會使它產生共振?

P是什么? PAIR? 很平坦,并放做的么?SKEW做的是不错,怎么做的。

pitch

测试9M看看。。说不定你的线已经很好了。。很稳定。。
和材料有关的你怎么改都没有用反而越改越没有头目;;
不只你们说的P 是否为pitch ;M3是否为衰减的第三频段。。
怎么解释?

外行小子问一下,你只测一组数据吗?还有的呢?

问题较多啊,找工艺哦

发图过来才可以分析的
