物理发泡同轴电缆周期性不均匀原理及实例分析

Theory and example analysis of periodic non uniformity in physically foamed coaxial cable

物理发泡聚乙烯绝缘是同轴电缆优良的绝缘形式。由挤塑过程所引起的微小的周期性不均匀将产生极大的反射损耗。本文结合实例对此进行了分析。

Physically foamed PE insulation is an excellent type of insulation. The micro periodic non uniformity produced in the manufacturing process will cause significant return loss. This paper, combined with practical example, analyses this problem.
