Materials and Fixtures for Measurements at 224Gbps

At 224Gbps data rates, test fixtures and PCB materials must improve.  Using a target of 67GHz for high-quality s-parameter measurements, various PCB materials and test fixtures are evaluated.  The evaluations include low-loss dielectrics, smooth PCB copper, and 1.85mm co-ax fixtures.  These are combined to make PCB trace measurements, plus co-ax and twinax cable measurements.  De-embedding […]

High Speed Electronics and Protection of Systems

Electronics are everywhere. From home to work place and when we travel, we rely on electronics for information, communication, productivity, entertainment and computing requirements. Less visibly, electronics is increasingly running vehicles, factories, managing our data and even connecting our home appliances. A common thread for all of these systems is the need to be always […]

Cascaded or End-to-End Interconnect Models: What Do We Give Up?

Reduced channel simulation times can be achieved by simulating PCBs and connectors separately then via cascading. However, this approach introduces impedance and crosstalk inaccuracies. This presentation demonstrates the differences through correlated simulation and measurement models. It then uses fields plots to devise mitigation strategies to maintain the increased simulation time while avoiding simulation inaccuracy.
