Packaging & Interconnects: Ultra-High Density Interconnects Tackle 15-GHz Applications

The UHD interconnect is a cable-to-board and cable-to-cable coax system for ultra-high-density applications with 15-GHz performance. Data rates up to 10 Gbits/s are supported. The interconnects consist of pc-board-mounted interposers/headers and coax cable that can be ganged together in multiposition housings down to 0.120-in. signal-to-signal spacings. Insertion loss is 0.90 dB/ft through 6 GHz using low-loss cables and 0.75 dB/ft using ultra-low-loss cables. The system comes in surface and edge-launch versions with multiple UHD contacts ganged together in a header (1 by 2, 1 by 4, or 1 by 8). Prices start from $14, and availability is within two weeks.
