Absorber, Magnetics & Shielding Design

Click to visit OrbelAchieving a successful RF design is often dependent upon proper implementation of shielding. The higher the frequency, the higher the power levels, or the more crowded the frequency band, the more difficult it is to design shielding that will provide the necessary level of isolation. Fortunately, there is a lot of design information available in the form of white papers, datasheets, and online write-ups.

For most applications, it is possible to obtain success using off-the-shelf components and well-tried methods. Sometimes, though, it is necessary to secure the assistance of engineers whose experience lies in the realm of shielding. Please consider contacting RF Cafe advertisers first when seeking such services.
