Calculate the Voltage Standing Wave Ratio (VSWR) from the reflection coefficient or return loss.

About this calculator
Overview
VSWR (Voltage Standing Wave Ratio) is a measure of how efficiently radio-frequency power is transmitted from a microwave source, through a transmission line, into a load.
💡
Pro Tips
Formula: VSWR = (1 + |Γ|) / (1 - |Γ|)
Γ (Gamma): Reflection Coefficient (0 to 1)
Ideal VSWR is 1:1, meaning no power is reflected.
A VSWR of infinity means 100% reflection (open or short circuit).

Fun Facts
"High VSWR can damage transmitters due to reflected power."
"VSWR can also be calculated from Return Loss (dB)."
"50 Ohm is the standard impedance for most RF systems."
