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.

Electronics, like automobile mechanics, has slowly become a lost art form for hobbyists because of the complexity of the systems, and the fact that most products can be purchased fully built and tested for far less that what they can be bought for in kit form. The advent of the grain of salt size surface mount components further complicated the aspiring hobbyist/builder because the specialized equipment necessary is expensive (hot air soldering/rework machine, microscope, solder paste dispenser, etc.). It is nearly impossible to even troubleshoot a modern consumer electronic device these days without access to a lab like the one many of us work (or worked) in.
Fortunately, there are still a still a handful of companies keeping the pastime alive by offering kits or partial kits. The sophistication of the kits does not come close to the color televisions or radio control units that Heathkit produced decades ago, but there are many building block circuit kits that at least take some of the work out of designing, building and testing your own custom creations.
