[ED Bookstore] RF Measurements For Cellular Phones And Wireless Data Systems
The title accurately tells what this book is about, but there is so much content here I do not know where to start. Essentially the book is about how to test and measure the wide range of wireless gear now being developed with an emphasis on cellular equipment. It is pretty rare to find a book on this subject and especially one that is reasonably up to date. Well, I’ve found one.

December 11, 2008[Ideas For Design] Micro-Structured Transducer Accurately Measures Pressure
Today’s micro- and nano-structured sensors boast excellent linearity, resolution, and wide measurement ranges. As a result, microelectromechanical systems (MEMS) are playing an increasing role in many more applications. This design describes a novel use of such a sensor—a non-contact differential variable-reluctance transducer (NCDVRT)—in the pressure port of a system. The application involves the selection of a stainless-steel membrane and...

George Frye was happily working at Tektronix on high-speed sampling oscilloscopes in 1970 when his hearing-impaired mom needed some help. “Her old Zenith hearing aid was getting a little cranky, ” said Frye. She took him up on an offer to build her one. “Transistors had just come onto the market, so I believed I could build it using transistors.” Although it turned out to be a little more complicated than he anticipated, Frye persisted and eventually...
