WebVoltage Standing Wave Ratio (VSWR), a unitless ratio ranging from 1 to infinity, expresses the amount of reflected energy at the input or output of the device. A value of 1 indicates that all of the energy passes through. VSWR is defined as the maximum voltage of the standing wave (E max) to the minimum voltage of the standing wave (E min ).

WebJul 7, 2024 · Some of the impinging energy will reflect to the source, with the amount dependent on the magnitude of the mismatch (Figure 2).
