Calculation Formula

VSWR = 10^(-Return Loss / 20)

Where:
Return Loss is the signal loss in decibels (dB) reflected by the transmission line. VSWR is the Voltage Standing Wave Ratio, a measure of impedance matching.

Understanding Return Loss and VSWR

Return Loss is a measure of signal reflection in a transmission system. It quantifies how much of the signal is lost due to impedance mismatch. Lower return loss values (in dB) indicate better impedance matching.

VSWR (Voltage Standing Wave Ratio) is a measure of impedance matching between a transmission line and its load. A VSWR of 1:1 represents perfect matching, while higher values indicate more significant impedance mismatches.

Example Calculation

If the Return Loss is 20 dB, the calculation would be:

VSWR = 10^(-20 / 20) = 10^(-1) = 0.1

This means the impedance matching is very poor (VSWR of 0.1 is unusual and indicates a short circuit condition).
