Coaxial Cable Impedance Calculator

Coaxial cables are used as the transmission lines in order to transmit the radio frequency signals. Coaxial cables usually have the impedance lies between 50 ohms or 75 ohms. It is the standardized impedance values with the ready made cables. Coaxial cable is a kind of electrical cable surrounded by tubular insulating layer further which is enclosed by tubular conducting shield. Use our online coaxial cable impedance calculator to compute the coaxial line impedance (Z0) value.

You can use the coaxial cable impedance formula mentioned above to calculate the impedance of the coaxial line by computing the capacitance, relative dielectric constant, relative magnetic permeability, inductance and propagation delay.
