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.
