The name of the RF coaxial connector is often defined by the inner diameter of the outer conductor, 3. 5mm, 2. 4mm, 1.85mm 1mm, etc. Or defined by the inner conductor diameter and the outer diameter of the outer conductor, such as 7/16, 1.6/5.6 connectors.

According to the standard characteristics of each RF connector, the following table shows the difference between RF coaxial connectors and frequency range.
