SWR Calculator Description

SWR Calculator is a handy program to help you calculate the errors in your microwave measurements. It consists of the Directivity Error Calculator, the Mismatch Error Calculator, and the Ratio-to-dB Calculator. The Directivity Error Calculator will show you the accuracy of a reflection measurement of an unknown impedance, based upon the directivity of the coupler used for the measurement. It is also a convenient way to convert a reflection coefficient to an equivalent standing wave ratio (SWR), return loss, or mismatch loss. The Mismatch Error Calculator shows the potential error in a transmission measurement due to imperfect source match and load match. It can also be used in a reflection measurement to determine the error caused by the mismatch between the measurement port and the unknown impedance. The Ratio-to-dB Calculator simply converts between voltage ratio, power ratio, and dB.
