Beamformer power divider/combiner with transmission lines distributed between MMIC and associated PC board

A beamformer includes an integrated-circuit power divider/combiner including a common port. A first transmission line extends from the common port to an individual port on the integrated circuit substrate. A first portion of a second transmission line extends on the substrate from the individual por...

description A beamformer includes an integrated-circuit power divider/combiner including a common port. A first transmission line extends from the common port to an individual port on the integrated circuit substrate. A first portion of a second transmission line extends on the substrate from the individual port to an integrated-circuit port. A second portion of the second transmission line extends from the integrated-circuit port vertically through plural layers of an underlying printed-circuit board stack. The characteristic impedances of the first and second portions of the second transmission line, and their combined length, are selected to match the impedance at the individual port to a standard impedance.
