Abstract
A differential cross-coupled power combiner in one aspect comprises a plurality of inputs, an output, a plurality of differential transmission lines each coupled between a corresponding one of the inputs and the output, and at least one set of additional differential transmission lines arranged in series between any two of the inputs. First and second ones of the additional differential transmission lines in the set are coupled to one another using a cross-coupling arrangement. Other aspects of the invention provide a differential cross-coupled power divider, communication system receivers and transmitters incorporating respective power combiners and dividers, and integrated circuit implementations of power combiners and dividers.
