Abstract
Aspects of the invention provide for an architecture and method for testing high frequency phase shifter arrays. In one embodiment, an architecture for testing a phase shifter array, includes: a plurality of power dividers, each power divider configured to receive an output from a phase shifter within the phase shifter array and split the output into a first signal and a second signal; a plurality of power clippers, each power clipper configured to receive the second signal and modify the second signal by limiting an amplitude of the second signal; a first power combiner configured to receive the first signal from each of the plurality of power dividers to generate a first output; and a second power combiner configured to receive the modified second signal from each of the plurality of power clippers to generate a second output.
