Quarter Wave Impedance Transformer Calculator

The quarterwave impedance transformation calculator is used to match an input and an output impedance at a given frequency for maximum power transfer.

Input impedance (Ohms)

Desired output impedance (Ohms)

Note: This transformer cable should be electrically one quarter wavelength, or a multiple of an odd quarterwavelength. The velocity factor of the transformer cable, and the connector lengths should be included in the quarterwave calculation.
