Commonly called "coax" (pronounced "co-axe"), the cable ... Typically with impedances of 50 or 75 Ohms, cables have different outside diameters and maximum capacities for operating voltage.

Coaxial cables are electrical cables with three or more layers ... Waveguides are structures which guide and direct different types of waves. In the case of electromagnetic waves, waveguides guide ...

They allow two different cable types to be joined together with a minimum amount of electrical gradation. Single-path data baluns provide an interface between older 75-ohm coaxial systems and 100-ohm ...
