Analysis of physical significance of reflection coefficient of equivalent signal source and application in power sensor calibration

A novel derivation procedure and constraint condition of the equation of reflection coefficient of equivalent source is presented. In the system of power sensor calibration, the reflection coefficient of equivalent signal source is an essential factor to figure out the calibration factor or effective efficiency. This paper gives a proof why the equivalent coefficient signal source can be used in power sensor calibration when the system of equivalent signal source is open-loop.
