Abstract
A stripline cross-over architecture includes a first stripline layer extending on a first side of a dielectric layer between a first signal input port and a plurality of first signal output ports. A second stripline layer extends on a second side of the dielectric layer between a second signal input port and a plurality of second signal output ports, crossing over the first stripline layer at a plurality of cross-overs of mutual overlap therebetween. The electrical lengths of the stripline layers are defined and the cross-overs are located such that electrical distances between the cross-overs and signal combination locations cause cross-coupled signals to cancel one another, when non cross-coupled signals are combined in phase.
