The ABCs of SWR, VSWR, Reflected Power and Return Loss

WebComplete Patent Searching Database and Patent Data Analytics Services. WebThe VSWR is a figure of merit for impedance match (or mismatch). In an attenuator, it is a measure of the deviation from 50 or 75 ohms of the component’s input and output impedances. A perfect match is represented by a VSWR of 1.0:1, while a worse-case mismatch is represented by an infinite VSWR of ∞ : 1. A VSWR that is slightly higher than
