Abstract :
A method is described to determine the complex equivalent reflection coefficient of RF sources using a mismatched power meter connected to a set of different phase shifting two-ports. The method is efficient, as only simple instrumentation is necessary, moreover, it is a broadband method, applicable to all types of sources and directly traceable to impedance standards.
