Our coaxial cable impedance calculator allows you to enter the outer diameter dielectric width, Inner conductor diameter width and either the dielectric constant or velocity of propagation (VoP) values. Entering these various values will calculate the impedance of the coax cable using the formula below. Pasternack’s online RF calculators with formulas and conversion tools, including this coax cable impedance calculating tool, are well suited for designers and engineers who need solutions for complex RF-related products and designs. This is especially true during the planning and design phase of projects where impedance figures from our formula would be useful.

Every Pasternack calculator or conversion page, including our coax impedance calculator, also includes a diagram or illustrated depiction of what the calculation is used for, besides providing you with a mathematical formula. As with our other calculators with formulas, you can plug in all the required variables to achieve the desired coax impedance figures. Based on those results, the calculator will highlight a ‘Find Related Products’ button that will direct you to our Pasternack items that meet your specific criteria.

As a leading manufacturer and supplier of RF, microwave and millimeter wave coaxial cable products, many industries around the world rely on Pasternack. Some of the industries that would want to use this impedance calculator include avionics, military electronics, IFF, SATCOM, ECM, industrial/manufacturing and oil/gas.

For complex mathematical formulas that need to be converted to simple conversions, many designers and engineers rely on our free-to-use radio frequency calculators from our vast library of RF, microwave and millimeter-wave calculators, including conversion tools.

Our complete range of radio frequency calculators, including metric-standard, link budget, coax cable, power, attenuation, frequency and plenty others, are the ideal tools that can accurately help in the measurement and provide you with accurate figures that you need for all your engineering requirements.

With hundreds of coaxial RF cables in-stock and ready to ship worldwide immediately, our coax capacitance calculator lets you calculate the impedance of a coax by allowing you to enter the outer diameter dielectric width and inner conductor diameter. With our handy calculator, you can choose from 50 Ohm, 75 Ohm,93 Ohm and 95 Ohm coaxial cables or 78 Ohm and 100 Ohm Twinax cables. You can also buy cable in bulk or construct your custom cable assemblies with our large selection of coax types to construct custom cable assemblies.

We understand that researching for and purchasing a product can be quite a hassle, especially if you have to visit multiple websites. That is why, for ease during the purchase process, our RF formula calculators have an innovative feature that allows designers and engineers to both research and purchase the product they need from one website itself.
