20150349735 | DIRECTIONAL COUPLERS HAVING VARIABLE POWER RATIOS AND RELATED DEVICES, SYSTEMS, AND METHODS - Variable power ratio (VPR) directional couplers that permit an amount of power directed to different outputs to be varied and managed. In some embodiments, the power ratio of the VPR coupler is represented by an equivalent coupling factor C′ corresponding to a conventional coupling factor C. The VPR coupler may include one or more variable reactive network (VRN) circuits, each configured to reflect a portion of power received from an input back toward the input, and to transmit a remainder of the power toward an output. An amount of power reflected and transmitted by the VRN circuit may be varied based on a control voltage applied to the VRN circuit. In one example, a plurality of VPR couplers can be arranged in series to create a versatile and simplified network for distributing signals to a plurality of end units. | 12-03-2015 |
