Return Loss vs VSWR conversion |
|
RL = 20log((VSWR+1) / (VSWR-1)) VSWR = (1+(10^RL/20)) / ((10^RL/20)-1) * RL = Return Loss Return Loss : This is the dB value of absolute reflection coefficient. It is rather curious concept of transmission engineering. This loss value becomes 0 for 100% reflection and becomes infinite for an ideal connection. Voltage Standing Wave Ratio (VSWR) : This is the ratio of maxmum voltage to minimum voltage in standing wave pattern. It varies from +1 to infinite. |
