我做的線材卻是在低頻M1、中頻M2、M3段稍底出一點(diǎn)點(diǎn),如何改善這個(gè)問(wèn)題點(diǎn)？
就底了2個(gè)DB！

導(dǎo)體的絞距減小一點(diǎn)，銅線用上公差。

鋁箔纏繞過(guò)緊也可能。

能不能把整份報(bào)告附上...
需要看圖形.

如何把圖片上傳到論壇上，又不需要GB下載！
能告訴我嗎？

目前已經(jīng)提高阻抗了 ，我把p=40時(shí)有一點(diǎn)m3下掉。謝謝大家的討論！

我將把設(shè)定的 p減低，m3就通過(guò)了 ，但問(wèn)題又來(lái)，低頻時(shí)出現(xiàn)沾邊;許多人說(shuō)我包帶有問(wèn)題，但我通過(guò)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(méi)有人參加討論呢？
加大p會(huì)不會(huì)使它產(chǎn)生共振？

P是什么？ PAIR？ 很平坦,并放做的么？SKEW做的是不錯(cuò)，怎么做的。

測(cè)試9M看看。。說(shuō)不定你的線已經(jīng)很好了。。很穩(wěn)定。。
和材料有關(guān)的你怎么改都沒(méi)有用反而越改越?jīng)]有頭目；；
不只你們說(shuō)的P 是否為pitch ；M3是否為衰減的第三頻段。。
怎么解釋？
