An Introduction to EMC Amplifiers
Broadband amplifiers are used to generate the high field strengths required by EMC radiated immunity testing standards. Although output power and frequency range are the two most important specifications used in selecting an EMC amplifier, the overall performance of an amplifier is often strongly affected by additional internal and external factors.
This white paper describes not only the basics but also intricacies, and discusses parameters and characteristics which have the greatest influence on amplifier performance. A technical overview of EMC amplifiers as well as a practical discussion of how amplifier class, compression points, VSWR, foldback, etc. impact amplifier performance in real-world scenarios.
