Abstract

A bandwidth of a directional coupler for RF power measurement can be significantly extended utilizing a capacitive or a resistive voltage divider and a ferrite core wound with a low number of turns, perhaps one turn on each side. Considerably wide coupling ranges are achievable by arbitrary choosing load values on the coupling side. Transmission line theory illustrates this principle of operation.
