Высокочастотные микроволновые и миллиметровые коаксиальные коаксиальные разъемы с кабелем
a coaxial cable can be considered a type of waveguide, specifically a cylindrical waveguide. In a coaxial cable, electromagnetic waves (typically radio frequency signals) propagate between the inner conductor and the outer conductor. For applications requiring higher bandwidth signals, N-type coaxial connectors are generally preferred due to their superior performance at high frequencies, while F-type connectors are commonly used for residential applications like cable TV and satellite connections.
