Preface

Radio frequency (RF) transmission is one of the oldest forms of electronics. From the days of Hertz and

Marconi, RF transmission has pioneered the art and science of electronics engineering. It has also served

as the basis for a myriad of related applications, not the least of which includes audio ampliﬁcation and

processing, video pickup and reproduction, and radar. RF technology has reshaped our national defense

efforts, radically changed the way we communicate, provided new products and services, and brought

nations together to celebrate good times and mourn bad times.

RF is an invisible technology. It is a discipline that often takes a back seat to other subjects taught in

colleges and universities. Yet RF transmission equipment has reshaped the way we live.

This book is intended to serve the information needs of persons who specify, install, and maintain

RF equipment. The wide variety of hardware currently in use requires that personnel involved in

RF work be familiar with a multitude of concepts and applications. This book examines a wide range

of technologies and power devices, focusing on devices and systems that produce in excess of

1 kilowatt (kW).

Extensive theoretical dissertations and mathematical explanations have been included to the

extent that they are essential for an understanding of the basic concepts. Excellent reference books

are available from this publisher that examine individual RF devices and the underlying design

criteria. This book puts the individual elements together and shows how they interrelate.

The areas covered by

The RF Transmission Systems Handbook

The

RF Transmission Systems Handbook

is divided into the following major subject areas:

•

. Common uses of radio frequency energy are examined and examples

given. This treatment includes an overview of RF bands, modulation methods, and ampliﬁer

operating classes.

•

. The operating parameters of semiconductor-based power devices are

discussed, and examples of typical circuits are given. Included is an outline of the basic principles

of bipolar and FET semiconductors, including potential failure modes.

•

. The basic principles and applications of gridded vacuum tubes are

outlined, and example circuits provided.

•

. The operating principles of classic microwave devices and new high-

efﬁciency tubes are given. This treatment reviews the basic concepts of klystrons, traveling-wave

tubes, and other microwave power devices.

range from broadcasting to electronic

counter-measures. The basic concepts and circuit types of all major RF applications are covered.

The generous use of illustrations makes difﬁcult or complex concepts easier to comprehend. Practical

examples are provided wherever possible. Special emphasis is given to radio and television hardware

because these applications provide examples that can readily be translated to other uses.

•

. The operation of hardware used to combine and

conduct RF power are explained, including coaxial transmission line, waveguide, hot-switches,

and circulators.

•

. An overview of antenna theory and common designs is given and basic

operating parameters are described. Examples are provided of antennas used in radio and TV

broadcasting, satellite service, and radar.

RF power technology is a complicated but exciting science. It is a science that advances each year. The

frontiers of higher power and higher frequency continue to fall as new applications drive new develop-

ments by manufacturers. Radio frequency technology is not an aging science. It is a discipline that is, in

fact, just reaching its stride.
