Broadband

When considering filters and filtered connectors to help eliminate noise issues in a system, determining the best EMI solution is based on the mechanical configuration of that system.

This brief article is geared towards EMC test practitioners who are tasked with specifying broadband RF amplifiers for RF immunity testing and need to quickly get up-to-speed on the key factors involved in the buying decision before actually making the purchase of an expensive amplifier.

Inductive loads and interrupted currents are an explosive combination. High voltages, arcing, and HF broadband noise are some typical effects. The phenomena behind these transients is complex, but it is not difficult to understand the fundamentals and how to minimize the effects.

This article examines the spread-spectrum frequency dithering technique to reduce the EMI noise from a SMPS.
