BSEE - KB3UON
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 ...

There are 1,000s of Pages Indexed on RF Cafe !
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.
Millimeter Wave Wireless Communications
In Millimeter Wave Wireless Communications, four of the field's pioneers, including Theodore S. Rappaport, Robert W. Heath, Robert C. Daniels, and James N. Murdock, draw on their vast experience to empower engineers at all levels to succeed with mmWave. They deliver fundamental, end-to-end coverage of all aspects of future mmWave wireless communications systems. The authors explain new multi-Gigabit per second products and applications, mmWave signal propagation, analog and digital circuit design, mmWave antenna designs ...
Antenna Physics: An Introduction
Delve deeper into antenna theory. Radio amateurs are familiar with antennas and use them every day to communicate on the air. We learned some basic antenna theory while studying for license exams, and most of us have built an antenna or two. We know the basics and turn to the ARRL Handbook, ARRL Antenna Book, and other general texts when thinking about our next antenna project. Antenna Physics: An Introduction is written to bridge the gap between basic theory and graduate-level ...
Practical Digital Wireless Signals
Practical Digital Wireless Signals, by Earl McCune, answers the question, "Do you need to know what signal type to select for a wireless application?" Quickly develop a useful expertise in digital modulation with this practical guide, based on the author's experience of over thirty years in industrial design. You will understand the physical meaning behind the mathematics of wireless signals and learn the intricacies and tradeoffs in signal selection and design. Six modulation families and twelve modulation types are covered ...
Elegoo Mega 2560 Arduino Project Kit
Arduino has been a sensation in the techie world for about a decade now. Not too long ago electronics 'starter kits' consisted of a battery, a solderless breadboard, a handful of Rs, Ls, and Cs, LEDs, a neon bulb, a couple simple ICs and transistors, and some jumper wires. Compare that to this kit with an Arduino microcontroller and code IDE, LCD, joystick, remote controller, motion and ultrasonic sensors, stepper motor controller, keypad, RFID module, and much more PLUS all the stuff you got with the old type starter kits - all for a paltry $60 (equiv. to $15 in 1977). Many add-ons available like an übercool robotic arm ...
Featured Book: Reflectionless Filters
Mini-Circuits has been running ads lately for 'reflectionless filters,' the likes of which are of great interest to frequency conversion circuit designers who like to place filters on RF and/or IF mixer ports. Normal filters have very bad out-of-band VSWR, which causes spurious signals to be reflected back to the mixer ports for 're-mixing,' causing even more spurious. The problem is typically addressed by placing attenuators between mixers and filters, which is undesirable from a noise figure perspective. This book by Mathew Morgan caught my attention because it deals with the issue ... (here is a good article in MWJ)
Featured Book: Federal Government Proposal Writing
News reports predict many opportunities for Federal defense and science development and production contracts in the coming years while America tires to rebuild its military, energy, and manufacturing base. Federal Government Proposal Writing was just released last week, so it is about as up to date as possible. It's been a couple decades since I was involved in defense proposal writing - it was a grueling and rigorous exercise. Author George Brown attended the School of Hard Knocks doing many such proposal efforts at Lockheed Martin and General Electric ...
Featured Book: Experimental Methods in RF Design
The revised first edition of Experimental Methods in RF Design is now available from the ARRL. Co-written and updated by Wes Hayward (of MicroSmith fame), W7ZOI, Rick Campbell, KK7B, and Bob Larkin, W7PUA, Experimental Methods in RF Design explores wide dynamic range, low distortion radio equipment, the use of direct conversion and phasing methods and digital signal processing. Use the models and discussion included in the book to design, build and measure equipment at both the circuit and the system level. Readers are ...
Classic Heathkit Electronic Test Equipment
"Heathkit was world renowned as a manufacturer of electronics in kit form. This book covers Heathkit's test equipment, starting with a brief history of Heathkit, an overview of the test equipment product lines and tips on buying and restoring vintage test equipment from sources like eBay. Separate chapters cover the major categories of component testers and substitution boxes, frequency counters, meters, oscilloscopes, power supplies, signal generators, tube testers and checkers and miscellaneous test equipment. Each chapter includes one or more 'In-Depth' sections ..."
The Official Arduino Starter Kit
Don't let not knowing how to pronounce "Arduino" (click for audio) keep you from joining in on an immensely popular hobby / professional opportunity (Tip: the word is Italian, so you need to make that circle with thumb and forefinger when saying "Arduino," like a chef does when talking about a delicacy). Many books and videos have been produced to help you get started - for less than $80. The Official Arduino Starter Kit walks you through the basics of using the Arduino in a hands-on way. You'll learn through building several creative projects. The kit includes a selection of the most common and useful electronic components with a 170-page book of 15 projects. Starting the basics of electronics, to more complex projects, the kit will help you control the physical world with sensor and actuators ...
Spectrum and Network Measurements
Keysight Technologies was kind enough to provide me with a copy of Spectrum and Network Measurements, by Robert A. Witte (SciTech Publishing). Its contents will soon be the subject of an RF Cafe Quiz. "This new edition of Spectrum and Network Measurements enables readers to understand the basic theory, relate it to measured results, and apply it when creating new designs. This comprehensive treatment of frequency domain measurements successfully consolidates all the pertinent theory into one text. It covers the theory and practice of spectrum and network measurements in electronic systems. It also provides thorough coverage of Fourier analysis, transmission lines, intermodulation distortion, signal-to-noise ratio and S-parameters ..."
