    Abstract: A microelectronics H-frame device comprising an RF crossover includes: a stack of two or more substrates, wherein a bottom surface of a top substrate comprises top substrate bottom metallization, and wherein a top surface of a bottom substrate comprises bottom substrate top metallization, wherein the top substrate bottom metallization and the bottom substrate top metallization form a ground plane that provides isolation to allow a first signal line to traverse one or more of the top substrate and the bottom substrate without being disturbed by a second signal line traversing one or more of the top substrate and the bottom substrate at a non-zero angle relative to the first signal line, at least one of the first signal line and the second signal line passing to a second level with the protection of the ground plane, thereby providing isolation from the other signal line.

    Abstract: An exemplary semiconductor technology implemented channelized filter includes a dielectric substrate with semiconductor fabricated metal traces on one surface, and input and output ports. A signal trace connected between the input and output port carries the signal to be filtered. Filter traces connect at intervals along the length of the signal trace to provide a reactance that varies with frequency. Ground traces provide a reference ground. A silicon enclosure with semiconductor fabricated cavities has a metal layer deposited over it. The periphery of the enclosure is dimensioned to engage corresponding ground traces about the periphery of the substrate. Walls of separate cavities enclose each of the filter traces to individually surround each thereby providing electromagnetic field isolation. Metal-to-metal conductive bonds are formed between cavity walls that engage the ground traces to establish a common reference ground. The filter traces preferably meander to minimize the footprint area of the substrate.
