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:
The companies listed here can supply your needs for any type of attenuator, be it fixed, variable, or programmable. They provide not only a stock of off-the-shelf models, but can also design and manufacture custom models for meeting specialty decibel values, form factor, power handling, or other unique parameters. There is also a lot of design information available in the form of white papers, datasheets, and online write-ups. Please consider contacting RF Cafe advertisers first for your needs.
