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 and furthermore, it is broadband, usable for all types of sources and directly traceable to impedance standards
