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.

Abstract: A phase shifter and method include a hybrid coupler being ground shielded. The hybrid coupler with reflective terminations connected to the hybrid coupler is configured to phase shift an applied signal wherein the reflective terminations include a parallel LC circuit.

Abstract: Improved phased array techniques and architectures are provided. For example, a linear phased array includes N discrete phase shifters and N?1 variable phase shifters, wherein the N?1 variable phase shifters are respectively coupled between adjacent output nodes of the N discrete phase shifters such that the N discrete phase shifters reduce an amount of continuous phase shift provided by the N?1 variable phase shifters. Each of the N discrete phase shifters may select between two or more discrete phase shifts. The N discrete phase shifters also preferably eliminate a need for a variable termination impedance in the linear phased array.
