Beamformer lattice for phased array antennas

摘要

In embodiments, an apparatus includes a beamformer including a plurality of inputs and a plurality of outputs, a plurality of input vias, and a plurality of output vias. Each input of the plurality of inputs electrically couples to a respective input via of the plurality of input vias. Each output of the plurality of outputs electrically couples to a respective output via of the plurality of output vias. The beamformer is included in a first layer, wherein the plurality of input vias are configured to electrically couple to termination trace ends of a plurality of hierarchical networks provided on at least second and third layers, and wherein the plurality of hierarchical networks comprises at least three hierarchical networks.
