Description of Terminology:
Coaxial connector

A coaxial connector is a component (input/output) used to connect coaxial lines and devices.
To transmit high-frequency electric power efficiently, it is important to ensure connection with reflection as low as possible in all frequency bands.

Accordingly, parameters for coaxial connector selection as as follows:

・Low reflection of connected surfaces

・Mechanical robustness and ability to withstand repeated use

・Operating frequency

・Cable (device) dimensions and structure
