Rohde & Schwarz White Paper: An Introduction to EMC Amplifiers - RF Cafe

February 19, 2019 - Rohde & Schwarz USA (R&S USA) has published a white paper entitled, "An Introduction to EMC Amplifiers." This white paper describes not only the basics of EMC amplifiers, but also intricacies, discusses parameters and characteristics that have the greatest influence on amplifier performance. It provides 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.

Broadband amplifiers are necessary for generating the field strengths required for most EMC radiated immunity tests. This whitepaper provides a brief overview of the role of amplifiers in EMC testing as well as a discussion of the parameters and characteristics which have the greatest influence on amplifier performance.

Over the last several decades electronic devices have played an increasingly important role in almost every aspect of everyday life--they have become virtually indispensable in business, industry, medicine, education and even in the home. All of these devices have the potential to interfere with, or suffer interference from, other electronic devices, either through radiated (over the air) or conducted (via cables) emissions. These interference effects can range from relatively minor disturbances, such as a barely perceptible audible buzz or visible flicker, to device failure and even permanent damage. Given the rapidly growing number of electronic devices, their often close proximity to each other, and their growing importance in our daily lives, it is essential that efforts be made in order to identify, measure, and limit or resolve interference between devices.

Founded more than 80 years ago, Rohde & Schwarz is one of the world's leading manufacturers of information and communications technology products for professional users. Initially focusing on RF engineering and RF applications in test and measurement, radiocommunications and broadcasting, the company has continually expanded its fields of activity over the past decades . In the meantime Rohde & Schwarz has also become one of Germany's largest manufacturers of IT security products.
