Claim Text:
1. A signal handling apparatus comprising: a first stage including one or more impedance transformers of a first type, for receiving one or more differential input signals from a signal source, matching an input impedance of the apparatus to an output impedance of the signal source, and combining the one or more differential input signals as first stage differential outputs; a second stage including one or more impedance transformers of a second type, for receiving the first stage differential outputs, combining the first stage differential outputs as a second stage output, and matching an impedance of the second stage output to an output device; and wherein the impedance transformers of the first and second stage are each implemented using meandering line conductive traces disposed on a substrate, wherein the impedance transformers of the second type are implemented as mirror image, vertically aligned, conductive traces disposed on opposite sides of a first substrate.
