Enter the Voltage Standing Wave Ratio into the calculator to determine the Return Loss.

## Vswr To Rl Formula

The following formula is used to calculate the Return Loss (RL) from Voltage Standing Wave Ratio (VSWR).

RL = 20 * log10((VSWR + 1) / (VSWR - 1))

Variables:

• RL is the Return Loss (dB) VSWR is the Voltage Standing Wave Ratio

To calculate the Return Loss, add 1 to the VSWR and divide the result by the VSWR minus 1. Then, take the logarithm base 10 of the result and multiply it by 20.

## What is a Vswr To Rl?

VSWR (Voltage Standing Wave Ratio) to RL (Return Loss) is a conversion used in radio frequency (RF) engineering to measure the efficiency of power transmission. VSWR is a measure of the mismatch between the load impedance and the transmission line impedance, which can result in power being reflected back towards the source.

Return Loss is a measure of the power reflected back to the source, expressed in decibels. Therefore, a high VSWR indicates a high level of power reflection, or low RL, and vice versa. The conversion between these two measures helps engineers optimize the power efficiency of RF systems.
