摘要
叙述电缆在使用中的几种阻抗匹配,推导出考虑信号源内阻时传输线上电压波的分布,分析了电缆长度与放大器反射损耗的关系,进而得出了最严段长。
Impedance matching in cable is described in this paper Expression on the distributionof voltage wave across transmission line is derived, considering the internal impedance. The relationship between cable length and amplifier reflection loss is analysed, and the most critical section lengthis calculated.
