RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

My Hobby Website:
Achieving 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.
