Connector & Adapter Definitions and Useful Formulas

VSWR

- Voltage Standing Wave Ratio. VSWR is a unitless ratio that describes how efficiently power is

transmitted through the connector. A lower VSWR value indicates better performance at a given frequency.

VSWR is easily derived from Return Loss.

Insertion Loss

- The loss of signal power (gain) resulting from the insertion of a device in a transmission line.

Insertion loss can be derived from the power transmitted to the load before the insertion of the component P

T

and the power transmitted to the load after the insertion of the component P
