    摘要: A high-speed cross-point switch is built on a preferably silicon substrate and uses bipolar transistor switching elements. Preferably, the bipolar transistors are SiGe bipolar junction transistors. Intersecting conductive input and output microstrips are preferably thinned at their intersections to reduce shunt capacitance between the coupled lines. It is also preferred that the input buffer be connected in cascode fashion with the switching transistors in order to create an amplification stage. The signal and its inverse are carried on balanced microstrip pairs in order to reduce electromagnetic field strength at the center of the balanced line pairs thereby improving isolation between two crossing balanced pairs.

    摘要: A switch matrix including a plurality of microstrip pairs arranged to form a grid and switches to couple the microstrip pairs where they cross. Each microstrip pair includes a first microstrip and a second microstrip for passing signals. The signals on the first and second microstrips are such that the electromagnetic forces produced by each one are canceled out by the other. By canceling out the electromagnetic forces, undesirable coupling between microstrips that cross and between microstrips and the substrate are minimized, thereby allowing inexpensive substrates such as silicon to be used.
