BASIC KNOWLEDGE OF COAXIAL CABLE

THE DEPENDENCE OF THE WAVE IMPEDANCE

The wave impedance is only depending on the outer diameter of the inner conductor, the inner diameter of the outer conductor and the dielectric constant of the intermediate dielectric. A vacuum is the best dielectric.

Question: Which is the right cable for my application?

For applications up to 1GHz we recommend the RG174, for applications up to 2.5GHz we recommend the RG179, RG188, RG187 or RG316. For applications above 2.5Ghz we recommend the use of low loss cable such as SS405, Multiflex_86 or CLF100. Due to the used materials and the cable structure, those cables are suitable for high frequencies (see illustration „Attenuation“).
