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 ...

My Hobby Website:
Each 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.
This authoritative new resource presents fundamentals of radar analysis including
the range equation, detection theory, ambiguity functions, antennas, receivers, SP, and chaff analysis for modern radars. This book addresses
details behind the detection probability equations and origins radar engineers commonly use to perform signal processor analyses. This book
consolidates discussions of
receiver design and analysis and treats areas of digital receivers not commonly found in other books. Packed with details on how to perform
radar range equation and detection analyses, RCS modeling, ambiguity function generation and antenna pattern generation. This book also includes
detailed analyses of coherent and non-coherent integration, design and analysis
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.
The ARRL Handbook
for Radio Communications is a valued reference for radio electronics and wireless communications. Since 1926, it has kept radio amateurs,
professionals, and experimenters immersed in applied theory and do-it-yourself projects. The ARRL Handbook covers a wealth of information: the
fundamentals of electronics and radio signals, construction practices, antennas and propagation, equipment and circuit design, and other useful
reference information. This 93rd edition of The Handbook continues to keep pace with the fast-moving technology employed around the world. Each
chapter is full of practical hands-on information to
RF and Microwave Grounding, by Eric Holzman, Grounding is a widespread and serious problem in microwave and RF engineering and, up
until now, there hasn't been a practical, authoritative resource dedicated to the topic. This first-of-its-kind volume offers professionals
a comprehensive understanding of the proper
grounding techniques to use when working on varied microwave circuit and antenna design projects. Practitioners learn what
problems can occur when grounding design is inadequate, and how to avoid them. The book covers a wide range of critical topics, from the fundamentals
of low frequency circuit theory and the differences between DC and RF short circuits...to grounding in active microwave component design and
The Satellite Communication Ground Segment and Earth Station Handbook, by Bruce Elbert. This updated and
expanded second edition reflects the state of earth station design and ground segment architecture. From international telephone network gateways
to direct broadcast home receivers, today's broad range of ground systems and devices require satellite communication engineers and business
managers to have a broad and sound understanding of the design and operating principles of earth stations and ground control facilities. This
book explores the delivery end of the satellite link and its relationship to delivery of services. Authored by a leading authority in the field,
the book provides engineers and managers with the knowledge
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.
The set of
six black tweezers have various tip shapes that are non-magnetic and have an anti-static finish.
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
Building, and Using Baluns and Ununs, by Jerry Sevick. Dr. Sevick, W2FMI, is widely known in amateur radio circles for his work with
transmission line transformers, baluns and ununs. This successor to the popular and authoritative Baluns and Ununs includes a
great deal of new tutorial material, and also includes new designs not in the previous book, along with crystal clear explanations of how and
why they work.

Advanced Computational Electromagnetic Methods and Applications, by Wenhua Yu, Wenxing Li, Atef Elsherbeni,
and Yahya Rahmat-Samii. It's not surprising that four people were needed to write this book! My eyes roll back in my head just before passing
out over the equations and program snippets included therein. "This new resource covers the latest developments in computational electromagnetic
methods, with emphasis on cutting-edge applications. This book is designed to extend existing literature to the latest development in computational
electromagnetic methods, which are of interest to readers in both academic and industrial areas. The topics include advanced techniques in MoM,
FEM and FDTD, spectral domain method

from Multiscale Rough Surfaces with Application to Wind Scatterometry, by Adrian K. Fung. "This resource explains and demonstrates the backscattering
properties of multiscale rough surfaces, and illustrates their application to establish the geophysical model function (GMF) needed in wind
scatterometry. This book also explains how the mechanisms of backscattering change with frequency and the incident angle on a multiscale surface
and how to recognize single scale versus multiscale surfaces - very useful information for those wanting to
Foundations of Antenna Engineering: A Unified Approach for Line-Of-Sight and Multipath, by Kildal Per-Simon.
This is the first textbook that contains a holistic treatment of antennas both for traditional antennas mounted on masts
(line-of-sight antenna systems) and for small antennas used on modern wireless devices such as smart phones being
subject to signal variations (fading) due to multipath propagation. The focus is on characterization, as well as
describing classical antennas by modern complex vector theory - thereby linking together many disciplines such as EM theory

The Art and Science of Ultrawideband
Antennas, by Hans Schantz, is a new publication released by Artech House. Along with theoretical formulations behind the engineering,
this book is chock full of examples of actual antennas with very unusual shapes, and there is a nice chart of the evolutionary timeline of
UWB antenna development that dates back to Maxwell in the 1800s (a nice wall chart candidate for the
lab if the publishers would enlarge and colorize it). "This comprehensive treatment of ultrawideband (UWB) antennas and time-domain microwave
engineering serves as an invaluable practical reference for anyone involved in antenna and RF design work. This authoritative volume enables

LeFun One Bluetooth
Phone Smart Watch wrist phone with NFC. Mate for Android phones like Samsung S3/S4/S5/Note 2/Note 3/Note 4 HTC Sony LG and iPhone 5/5C/5S/6/6.
Unlike the Apple Watch, this model is capable of functioning as a stand-along cellphone with a SIM card installed. You can send and read texts,
make or receive calls on your watch. Simply like a GSM cell phone. Without SIM card, it works as a cell phone companion, receiving and making
calls, getting texts via Bluetooth. Unlike that 'other' watch priced at $349, Android smart watches can be bought for under $75.
