Sean Cahill
VP Technology, Bridgewave Communications
February 23, 2010 | 12:00 to 01:00 | 521 Cory Hall, Hogan Room
Host: John Huggins
This talk will describe a new interconnect approach, MicroCoax, that applies micro-fabrication technology to create high-bandwidth interconnects for increasingly higher frequency digital and analog electronic systems. Prototype devices show excellent performance over DC-100+ GHz frequency range. Transmission line losses less than 0.5 dB, 160 µm pitch, and cross-talk isolation of approximately 40-50 dB from DC-50 GHz are demonstrated. The technology has implications for improved package design and these design implications will be discussed. In particular, low-cost QFN packages capable of operating to 80 GHz and beyond will be shown. Such a package could propagate 150 Gbps data-rate signals on a single channel.
