Voltage
Formulas
VSWR
RL(dB) = 20×log₁₀((VSWR-1)/(VSWR+1))
VSWR
Example: VSWR=3.0 → RL = 20×log₁₀(2/4) = -6.02 dB
VSWR
VSWR = (1+10^(-RL/20))/(1-10^(-RL/20))
CalculateVSWR
Example: RL=-6dB → VSWR = 3.0
VSWR Coefficient
Γ = (VSWR-1)/(VSWR+1)
Coefficient
Example: VSWR=3 → Γ = 0.5
CoefficientVSWR
VSWR = (1+|Γ|)/(1-|Γ|)
CoefficientVSWR
Example: Γ=0.5 → VSWR = 3
