Application Notes & Technical Papers
by Company / Source Name

RF Microwave Wireless High Frequency Application Note & Technical Paper Websites by Company Name - RF CafeThese application notes on vendor sites are some of the fastest moving targets on the web. Since numerous copies of these PDF files are located all over the Web, I assume the companies do not mind since they ultimately get credit for them. Therefore, I will break from my policy of not hosting copyrighted material on RF Cafe and keep local copies of the applications note I deem most useful to RF Cafe visitors. That will avoid the annoying occurrences of broken hyperlinks to the app notes. If you try to visit one of these links and it is dead, please make an attempt to determine the new URL and notify me. If you are the copyright owner of any of these papers and object to my keeping a copy, please let me know and I will remove it immediately. Thank you. Due to how large the original page has grown, multiple pages are now used.

      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 ...
