Obsolete, Hard-to-Find, and Aftermarket Components & Parts
Manufacturers & Services

As the rate of technological advances increase at an ever faster pace, obsolescence occurs at an ever increasing pace, too. In highly critical areas, some manufacturers continue production for replacing worn out or failed parts. In most instances, production by the original company is halted after a short and another independent manufacturer contracts to do the job. Other companies design and produce their own form/fit/function substitute components, and still others rely on buying excess inventory to supply the needs of legacy systems. This page is a collection of sources for such needs.

About RF Cafe

    Kirt Blattenberger,


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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
