※ 引述《greed0331 (...)》之銘言: : 請問是什麼原因傳輸線特性組抗大都是50歐姆.... : 單純只是因為規格嗎...還是有什麼特殊的原因..比如跟阻抗匹配之類的有沒有關係阿 : 謝謝... 手邊的資料: for coaxial line -attenuation is lowest when characteristic impedance for coaxial airlines is 77 ohms. -power handling capacity peaks at when characteristic impedance for coaxial airlines is 30 ohms. 所以取中間值 就大約是50 ohms -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.112.48.80

login22:what's the power handling capacity??? 10/08 11:49
ihlin:材料本身能承受的power,多和BreakDownVoltage有關 10/08 14:50
