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...

Of course you know that there are hundreds - maybe even thousands - of useful instructional videos available on
YouTube and/or company and college websites. They can be a valuable resource for information on design, test,
implementation, and theory on nearly any topic imaginable. The busier you are, the less time you have to watch one
of the videos simply for review or general knowledge enhancement. However, some of the webinars, classroom
lessons, company presentations, and privately done videos are very useful when you have a specific problem to
solve. A lot of digitized productions from old armed forces and other government entities can be really useful
even in black-and-white. Here are a few videos that I have viewed recently which might be of interest to you, but
even if not these, surely there is some topic you have been meaning to look up but haven't gotten around to it.
Webinar: PIM Testing DAS - Which Frequency Band Should You Use?
Presented by Tom Bell, Sr. Product Manager.
Passive Intermodulation is a phenomenon caused by nonlinear properties of mechanical interfaces like coaxial cable
connectors, antenna bolts and rivets, etc.
Chip Antenna Presentation
Presented by Vishay.
Introduces chip antenna configurations for 400-1,000 MHz. The web page also has numerous other related product
