射频同轴电缆的使用频率正在不断地向更高频率以及微波波段发展,现代的射频电缆可以使用到高达18GH_2的频率下,这代表着电缆质量日益改善的结果。一般说来,同轴电缆可以使用的频率范围,受到对电缆的低衰减,低驻波要求的限制,如果通过结构设计以及工艺加工的改善,排除了上述两因素的限制,则电缆最终还要受到高次波出现的极限频率的限
The frequency of use of RF coaxial cables is continually evolving towards higher frequencies as well as microwave bands, and modern RF cables can operate at frequencies up to 18 GHz, representing an increasingly improved cable quality. In general, the frequency range over which coaxial cable can be used is limited by the low attenuation and low standing wave requirements of the cable. If these two factors are excluded by structural design and process improvement, the cable eventually has to Limited by the limit frequency at which higher orders appear
