The article provides a detailed procedure in the assembly of rf coax cables for use in rf and microwave communications. The connection assembly and the transmission and reflection coefficients become very important at these frequencies.
You provide Outer Diameter (D), Inner Diameter (d), and Permittivity (εr) values then the calculator gives you Zo (ohms), fc Cut off frequency(GHz), C/length (pF/m), and inductance L/length (nH/m). Other tools are available for impedance measurement, dbm to milli watt converter, reflection coefficient calculator, etc.
The page offers a tool for configuring custom co-axial cable by specifying the end connectors, cable type, and required insertion and return losses. It can be saved in pdf format and the spec may be emailed after completing the configuration.
