前言特性阻抗是同轴射频电缆首先要考虑的最重要的参数。不论是选择使用同轴电缆还是设计制造同轴电缆都是从特性阻抗开始的。一般射频电缆特性阻抗及其公差为50±2;75±3;100±5欧姆。国际电工委员会(以下简称 IEC)规定精密型射频电缆特性阻抗公差为50±1; 75±1.5。因此精确计算同轴电缆的特性阻抗及电感对电缆的设计是重要的。对同轴电缆而
Introduction The characteristic impedance is the most important parameter to be considered first for coaxial RF cables. Whether you choose to use coaxial cable or coaxial cable design and manufacture from the beginning of the characteristic impedance. General RF cable characteristic impedance and its tolerance is 50 ± 2; 75 ± 3; 100 ± 5 ohm. International Electrotechnical Commission (hereinafter referred to as IEC) provides precision RF cable characteristic impedance tolerance of 50 ± 1; 75 ± 1.5. Therefore, accurate calculation of coaxial cable impedance and inductance of the cable design is important. For coaxial cable
