VSWR Conversion to Reflected Power

VSWR
This application note from Exodus Advanced Communications details the relationship between Voltage Standing Wave Ratio (VSWR), Return Loss, Reflection Coefficient, Mismatch Loss and delivered power in RF systems. It explains how impedance mismatches lead to reflected power and reduced system efficiency. The document provides formulas for calculating these parameters and presents tables showing the impact of VSWR on delivered power at different forward power levels – specifically 10W, 100W, 250W, and 1000W. For example, a VSWR of 2.0 with 100W forward power results in 89W delivered and 11W reflected, while at the same VSWR but 1000W forward power delivers 890W and reflects 110W.
