Design

Should the reference (i.e., ground) plane be split into two separate sections and a ferrite bead installed between them to prevent unwanted radio frequency emissions? Let’s examine why this practice is not a good idea and should be avoided at all costs.

The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and straightforward design process, though such alignments may readily be modified to utilize pre-defined component values.

There is often confusion about the interaction between IC-level component ESD protection and the appropriately required system-level ESD protection strategy.

In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.

This month’s column is the last of three parts devoted to designing, testing, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

Discover the most important post-layout elements when selecting a SI/PI software simulation package.

This is the second of three articles devoted to the design, test, and EMC immunity evaluation of multilayer PCBs containing analog circuitry.

Secure facility designs often comingle ICS/ICD-705 and NSA 94-106 performance requirements creating project confusion with significant design and cost implications. This article focuses on bringing some clarity to the differences between ICS/ICD-705 design guidance and NSA 94-106 performance requirements. The related secure facility design and construction process is also reviewed.

Advance military and avionics technologies must be designed to address a range of complex specifications. The use of multiport connectors can provide significant benefits compared with conventional RF/microwave cable assemblies.

While the selection of components in electrical equipment plays a crucial role, a sound understanding of the characteristics of safety-critical and high-integrity components can provide valuable information about the ways to advance and achieve safety goals.
