**VSWR**

What is VSWR?

VSWR, or Voltage Standing Wave Ratio, is a measure of impedance matching of a load to a source. It quantifies the standing wave ratio in a transmission line and is defined as the ratio of the maximum to the minimum voltage along the line. A VSWR of 1:1 indicates perfect matching, while higher values indicate reflections and power loss. VSWR is commonly used in radio frequency (RF) and microwave systems to assess antenna performance, cable connections, and amplifier matching.
