VSWR calculator

This tool performs real-time and precise data calculations between Voltage Standing Wave Ratio VSWR, Return Loss, Reflection Coefficient and Mismatch Loss.

-
\[ \text{Reflection Coefficient: } \gamma = \left|\frac{VSWR - 1}{VSWR + 1}\right| \]
\[ \text{Return Loss: } RL = -20 \log_{10}|\gamma| \]
\[ \text{Mismatch Loss: } ML_{dB} = -10 \log_{10} \left(1 - \left(\frac{VSWR - 1}{VSWR + 1}\right)^2 \right) \]
\[ VSWR = 20 \cdot \log_{10} \left(\frac{RL + 1}{RL - 1}\right) \]
\[ \text{Impedance: } Z = Z_0 \cdot \left(\frac{1 + RL}{1 - RL}\right) \]
\[ \text{Admittance: } Y = Y_0 \cdot \left(\frac{1 - RL}{1 + RL}\right) \]
