Reflection Coefficient to Return Loss Formula Conversion Calculator is a useful online conversion calculator for converting reflection coefficient to return loss. Enter the value of the reflection coefficient and the calculator will compute the return loss. Bonus: The calculator also calculates VSWR and mismatch losses.
Formula
Where
Γ = Reflection Coefficient
LR = Return Loss
Solved Examples
Convert the reflection coefficient value of 20 to return loss
LR = -20log10Γ = -20log10(20) = -26.02
