Voltage Standing Wave Ratio

Computes RF transmission line mismatch parameters from VSWR: reflection coefficient Γ, reflected power (% and dB), and mismatch loss (dB).

Inputs

Voltage standing wave ratio — must be ≥ 1 (1 = perfect match, ∞ = total reflection)

Results

Reflection Coefficient0.000e+0Voltage reflection coefficient (0 = no reflection, 1 = total reflection)
Reflected Power0.000e+0%Percentage of incident power reflected back
Reflected Power0.000e+0dBReturn loss in decibels (negative value — more negative = better match)
Mismatch Loss0.000e+0dBInsertion loss due to impedance mismatch in decibels (negative value)
