Silicon Labs isolators are designed for minimal radiated emissions. Review radiated emissions standards, typical sources and techniques for reducing effects in circuits.
We discuss sources and coupling mechanisms for radiated emissions in isolation designs.
All conductors at a non-zero voltage or carrying an electrical current act as transmitting antennas that source energy into the surrounding environment in the form of near-field electric fields, near-field magnetic fields, and far-field electromagnetic fields.
Energy from these fields can couple onto other conductors and circuits within the equipment as well as radiate into the environment outside of the equipment.
