    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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Are you old enough to remember when in order to make a measurement on a circuit board it was necessary to physically connect an oscilloscope probe to a trace or component lead? "Wait," you say, "What are you talking about? You still do have to physically connect a probe." Right you are, but 50 years from now your progeny will be asking that question, just as today I ask you do you remember when in order to get a "screen shot" of an o−scope or spectrum analyzer display it was necessary to connect a camera to the front of the CRT? Some instruments had an(a) output port(s) for driving a pen plotter, but getting a plotter set up and calibrated was often more work and frustration than hanging a camera on the front. Most of the cameras used Polaroid film packs to enable "instant" pictures. Getting a good image usually took a couple tries. Scope cameras were still in common use when I entered the electronics world in the 1970s. It really wasn't until the later 1980s or early 1990s that printers could be hooked up to newer test instruments with a GPIB or parallel output port.
