特性阻抗是射频电缆选择时,首先要考虑的最重要的参数。均匀传输线的特性阻抗,代表该线路在匹配条件(或行波状态)下工作时,沿线的电压与电流之比值。传输线匹配的条件是线路终端的负载的阻抗正好等于该传输线的特性阻抗,此时没有能量的反射,因而有最高
Characteristic impedance is the most important parameter to consider when choosing a radio frequency cable. The characteristic impedance of a uniform transmission line represents the ratio of voltage to current along the line when the line is operating under matching conditions (or traveling wave conditions). The condition of the transmission line matching is that the impedance of the load of the line terminal is exactly equal to the characteristic impedance of the transmission line, and there is no reflection of the energy at this time and thus has the highest
