Practical RF Design Manual
[Practical RF Design Manual by Doug DeMaw (Milton F "Doug" DeMaw). 1997. MFJ Publishing. 2nd Edition 1997 : 246 pages. ISBN 1-891237-00-4]
For many years I was an amateur radio - "ham radio" - operator, beginning when I was 13 years old and going up until I was about 40 years old. For those who are interested, my call sign was WA6FEB and I held an Extra Class ham radio license (this is the highest classification). My fascination with radio was fostered by my step-father, the late Sam Martin (WB6WZN, later N7TBV), who had learned his electronics and radio theory while serving in the US Navy.
Sam had many years’ worth of a magazine called QST, which was one of the premier journals available for ham radio enthusiasts. Doug DeMaw, the author of the book under review here, was a prolific contributor to QST and to other ham radio publications. I was (and remain) a huge fan of his writings, especially his transmitter and receiver projects for ham radio folks.
What I did not know then, but have come to learn, is that DeMaw was truly a world-class electrical and electronic engineer. He was known to much of the world as a ham radio person first and foremost, but he was a professional engineer who had an extraordinarily broad grasp of all aspects of radio transmission and reception, covering all power levels from the very tiny (what we in the ham radio community called QRP, or low-power, operation, usually less than 1 watt) to the industrial (the 50,000-watt and 100,000-watt “clear channel” broadcasts from commercial radio stations, for example). DeMaw was well-versed in design considerations spanning operating frequencies from the US AM broadcast band (560 KHz to 1600 KHz) all the way up to the UHF range (where television broadcast channel 14 begins in the US, or around 470 MHz and beyond). His knowledge went beyond component-level design of devices to include the design and tuning of antennas and other auxiliary devices to aid in the radio experience.
All of this knowledge is subsumed under the aegis of RF - radio frequency. RF in modern terms is usually linked to RF ID chips, which are becoming quite common in scenarios that require tracking (such as shipment packages), but this is a very restricted window into the RF world. To really see just how vast an enterprise RF electronics is, one might consult this book.
This volume is truly a gem. I dearly wish I had access to it back in the early 1970s when I was first getting into radio. It would have illuminated a lot of practical design issues for me, especially on the design of receivers. Receivers are generally more complicated and finicky than transmitters – it’s easier to generate radio energy and cast it out into the universe than it is to gather it in and make sense of it. This book leads the reader through 7 broad-based topics and roughly 40 overall subsections within those topics, starting with transmitter and receiver fundamentals and leading the reader through considerations related to power regulation, signal quality, the use of different types of components for different frequencies of operation and different power levels, and so on.
Unlike much of DeMaw’s writing with which I had been previously acquainted, this book is definitely not a book for someone looking to do a home project. There are no comprehensive instructions on assembling or testing transmitters, receivers, or other associated machinery. This book is written for a true engineer who wants to become familiar with many (most) of the gotchas that accompany real in-the-trenches electronic engineering work. And in this vein, this book is as useful to a professional radio engineer (such as someone who is the engineer-in-charge at a radio or television station, for instance) as it is to a radio hobbyist. It is also not the sort of book from which to learn first principles of electronics; for this, there are many more suitable books that introduce electronics at the most elementary level (Ohm’s Law, Kirchhoff’s Law, how vacuum tubes and transistors work, what makes oscillators work, and so on). This book assumes that the reader already has some engineering skin in the game, as the saying goes.
Whom would I recommend this book to? Anyone who wishes to know something about electronics that precedes the modern all-digital era where whole systems are embedded on integrated circuit (IC) chips. While those circuits may make for easier and more controlled design, they take away a lot of the learning, guesswork, and outright fun of figuring these things out for yourself. DeMaw’s work hearkens back to what many of us current and former ham radio people think of as a sort of golden era of communications – a time before cell phones and before email.
A couple of comments about the text itself:
There are some typos both in the text and on the many diagrams. For the most part these are easy to spot if you are already versed in basic electronics, but they would be profoundly confusing to someone who doesn’t know what they’re looking at. Anyone who doesn’t know how to read a basic schematic diagram of a circuit will not find this volume very helpful.
Bearing in mind that some of the material in this book dates to the 1970s and 1980s, it is possible that some of the actual components cited in the text no longer exist or are not easily available. Happily, the author describes them in sufficient detail that a modern engineer or hobbyist can find current components whose characteristics match what DeMaw had at his disposal when the book was written. DeMaw was fairly fastidious about describing the important pieces of each circuit or circuit fragment in the book. One needs but to pay attention to the text to make the connection.
I was delighted to read through this volume. I am not currently an active hobbyist, but as I near retirement age, I am giving a return to ham radio serious thought. With that in mind, this book will be an invaluable title in my collection when I once again wield a soldering iron and set out to make some more home-brew radio equipment as I did so many years ago.

Wireless Wonders: Unraveling the Magic of IR and RF Transmitter and Receivers
In a world where wires seem to be disappearing faster than a magician’s rabbit, the spotlight is shining brightly on the magic of wireless communication. If you’ve ever marveled at how your TV remote controls the channel or your car key unlocks the door from a distance, you’ve witnessed the enchanting performance of Infrared (IR) and Radio Frequency (RF) transmitters and receivers.
Let’s dive into the captivating world of these electronic wizards and discover how they make the seemingly impossible, possible.
IR Transmitters and Receivers: The Invisible Light Symphony
Imagine your TV remote as a maestro, conducting an orchestra of invisible light. This is precisely what happens with IR transmitters and receivers. IR technology uses light waves just below the visible spectrum to transmit information.
When you press a button on your remote, the corresponding command is translated into a unique pattern of infrared light pulses. The IR receiver on your TV picks up these pulses and decodes them, instructing your television to change the channel, adjust the volume, or perform other tasks.
IR technology is not just confined to the living room. It’s the wizard behind many gadgets, from air conditioners to digital cameras. However, there’s a catch — IR signals require a direct line of sight between the transmitter and receiver. That’s why you often find yourself pointing your remote at the TV for it to work its magic.
RF Transmitters and Receivers: The Wireless Symphony
Now, let’s step into the realm of RF technology, where the magic of wireless communication truly shines. Unlike IR, Radio Frequency doesn’t demand a visual connection. It dances through walls, ceilings, and even furniture to deliver its commands.
Your car key fob is a prime example of RF technology. When you press the unlock button, the RF transmitter in your key fob sends a signal to the RF receiver in your car, triggering the doors to unlock. This enchanting dance of signals happens through the air, making RF technology the go-to choice for applications that require a broader range.
One of the RF technology’s superpowers lies in its ability to operate at different frequencies. This flexibility allows various devices to communicate simultaneously without interference, creating a wireless symphony where each instrument plays its unique tune.
The Harmony of Everyday Applications
Now that we’ve peeked behind the curtain of IR and RF technology, it’s clear that these electronic maestros are orchestrating the harmony of our daily lives. From home entertainment systems to car security, they’re the unsung heroes making convenience and efficiency possible.
So, the next time you change the channel with your TV remote or unlock your car with a click of a button, take a moment to appreciate the invisible symphony of IR and RF transmitter and receivers working their magic behind the scenes.
In this era of wireless wonders, it’s these electronic wizards that remind us that the future is not just wireless; it’s enchantingly untethered.

IR (Infrared) transmitters and receivers use infrared light for communication. RF (Radio Frequency) transmitters and receivers use radio waves. Both transmit signals wirelessly over short or long distances.
