Abstract
A directional coupler includes an input connector, an output connector, and at least one tap connector. The directional coupler also includes a primary line connecting the input connector to the output connector and configured to carry an RF signal and an AC signal, and a secondary line connecting the primary line to the at least one tap connector and configured to carry a split off portion of the RF signal. The directional coupler also includes a tapped line circuit which is inhibited from carrying the AC signal. The mainline transformer includes a ferrite element surrounding the primary line and which is split in at least one location to include a gap of non-magnetic material that inhibits saturation of the ferrite element.
