Abstract
A power divider/combiner circuit with coupled inductors is provided. With coupled inductors, the new circuit topology exhibits broader bandwidth for insertion loss, port matching and isolation compared with traditional power divider/combiner circuit topologies. The coupled inductors can be implemented for single-stage low-pass networks, multi-stage low-pass networks, or multi-stage wide-band networks. For example, the power divider/combiner circuit includes a first coupled inductor circuit coupled to an input terminal that provides a first signal path to a first output terminal, and a second coupled inductor circuit coupled to the input terminal that provides a second signal path to a second output terminal. Each of the coupled inductor circuits include multiple inductors that are tightly and positively magnetically coupled to one another. Each of the coupled inductor circuits provides an output signal that is based on a transfer function that includes a coupling coefficient of the corresponding coupled inductor circuit.
