ABSTRACT:
A directional coupler with a first and second transformer, having their primary windings connected in series, provides a sample of the current flow through the series connected primary windings. A third transformer provides a voltage sample of the voltage that results from the current flow through the primary windings of the first and second transformers. The voltage sample and the current sample are vectorially combined by a vector adder to obtain a first signal that is representative of the reflected power components of the current and voltage samples and also to provide a second signal that is representative of the forward power components of the current and voltage samples.
