Match different impedances by attenuation.

By making use of an asymmetrical resistive attenuator you can match different impedance's, or just use it as an normal attenuator calculator when both the input and output impedance's are equal.With this tool you are not limited to 50Ohms, but any impedance can be selected making this calculator a very flexible tool.

With this calculator you can go to higher or lower impedance's from the input impedance. From the difference in impedance between the input and output, and the required attenuation level, a minimum required attenuation is calculated to obtain a good level of matching on both sides.
