摘要
衰减是射频(RF)同轴电缆最重要的传输特性。外导体皱纹深度及泡沫聚乙烯(PE)的介质损耗角正切tgδ是影响皱纹外导体泡沫PE绝缘同轴电缆衰减的主要因素。浅皱纹结构及净化介质材料是降低该电缆衰减值的有效途径。
Attenuation is the most important transmission characteristic of RF coaxial cables. The corrugation depth of the outer conductor and the tg 6 of foamed PE are the main factors affecting the attenuation of the coaxial cable with corrugated outer conductor and foamed PE insulation. Shallow corrugation and the cleaning of dielectric material are the effective approaches to reduce the attenuation of such kind of coaxial cables.
