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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

Featured Product Archive - 19

Artech HouseCambridge University PressEach week, I select a new book that is relevant to engineers, scientists, students, hobbyists or managers. Most of the time they are sold through Amazon (I earn a few pennies on each sale), but when possible, I present books that are available in an e-book format that can be downloaded for free. The latter are much less available. After all, most people like to be paid for their work, as I'm certain that you do, too.

Note: I just began archiving these picks in May of 2009, but they have been going on since about 2003.

Effective Expert Witnessing: Practices for the 21st Century

Effective Expert Witnessing: Practices for the 21st Century - RF CafeEffective Expert Witnessing: Practices for the 21st Century, 5th Edition, by Jack V. Matson, comes highly recommended by the good folks at IMS ExpertServices. They are the origin of all the BullsEye articles I post that provide insight into real court cases involving expert witnesses. After I recently posted "Tips from an Expert Witness Recruiter on Getting Hired," written by Mr. Toby Edwards, I wrote to ask whether there is a book that would be particularly good for someone either already engaged in or contemplating being engaged in providing expert witness services. This book was the response.

Tweezers for Working with Tiny Surface Mount Components

If you work with surface mount components, you know how challenging it can be positioning and holding them while soldering and unsoldering. Having a good pair of tweezers can make the difference between a good experience and a disaster. These two types of tweezers can definitely make you life better, and they're very inexpensive. Non-Magnetic Tweezers Anti-static Black (6 pcs.) - RF CafeThe set of six black tweezers have various tip shapes that are non-magnetic and have an anti-static finish. Ceramic Tweezers - RF CafeThe white-tipped tweezer uses ceramic material that can stand soldering type temperatures without transferring the heat to your fingers. At less than $5 each, you can outfit your home and work labs with quality tweezers and still have money left over to donate to RF Cafe ;-)
