Preface
The ninth edition provides new knowledge in the fields of satellite technology, space communication, microwave science, telecom-
munication, global positioning systems, frequency data, and radar. Also revised and updated were the chapters on intellectual prop-
erty and patents, probability and design, power electronics-rectifiers, filter, and power supplies, properties of materials, units.
constants and conversion factors, active filter design, antennas, integrated circuits, digital signal processing, and surface acoustic
wave devices.
I am sure that as you read this text you will also appreciate the hard work and expertise of these authors. This edition of Reference
Data for Electrical Engineers will continue its tradition of being an important reference text for all electrical engineers.
Highlights of Updated Chapters
Chapter 1: Radio Frequency Spectrum Management and Time Frequency Standards - by F. Matos
ITU information is available on the web for download.
While the Omnibus Budget Reconciliation Act did open the door for auctions, it only authorized them for a short time. A bet-
ter reference is: Radiofrequency Spectrum Management: Background, Status, and Current Issues, January 30,2001, Richard
M. Nunno, Congressional Research Service, Washington, DC Order Code IU30829.
The GPS Time Scale began on January 6, 1980 and is not adjusted for leap seconds. Therefore, it differs from UTC by the
number of leap seconds that have occurred January 6, 1980. As of June 2001, GPS Time is 13 seconds ahead of UTC.
Much of the data in this chapter cross-references with Chapter 37 on GPS.
The updates on GPS before and after S/A was turned off are quite good, as is the discussion of the merits of different types of
atomic clocks.
For up-to-date GPS information, the web address for the United States Coast Guard Navigation Center is:
http://www.navcen.uscg.gov/
For the readers’ reference: A nanometer is 10-9 meter. The meter is defined as: the length of the path traveled by light in vac-
uum during a time interval of 1/299 792 458 of a second.
The constant for the speed of light can be found at: http://www.physics.nist.gov/cgi-bin/cuu~alue?clsearch-fo~light
Chapter 3: Units, Constants, and Conversion Factors - by E. Mechtly
* Temperatures are discussed in the context of Table 2, SI Base and Derived Umts. See entries for Kelvin and for degree Celsius
in Table 2.
Many tables were updated. The style information on how to correctly express different units is a resource that many will be
likely to use in the future.
The values for constants have been updated and citations including worldwide web addresses have been added.
Chapter 4: Properties of Materials - by E. Mechtly
- The most current versions of the table of Superconducting Materials can be found at internet sources such as the NIST Super-
conducting Materials Database at http://www.ceramics.nist.gov/srdo r by the “High-T (critical) Update,” sponsored by the
Argonne National Laboratory at http://www.iitap.iastate.edu.
The tables on wires, gauges, and drills sizes lie on the interface between engineering and shop technology. Here, again, the
internet offers a multitude of equivalent sources. For example, a web search for “wire gauge” or “AWG’ yields many sources,
Likewise, does a search for “drills.”
Chapter 10: Active Filter Design - by R. Schaumann
* GHz applications and three amplifier filters sections have been updated
- The chapter now has additional detail on switched filters.
Chapter 14: Power Electronics-Rectifiers, Filters, and Power Supplies - by 0. Pauk
- Manufacturer’s data sheets are now available for free download from the web as PDF files.
* Information on switching power supplies is of high quality and is up-to-date,
Chapter 16: Electron Tubes - by D. Abe, R. Abrams, B. Danly, H. Freund, K. Jensen, B. Levush, R. Myers, R. Parker, J. Shaw.
A. Shih, and J. Yater
For more than fifty years, the venerable vacuum tube has proved to be the technology of choice for many applications. The
advent of solid-state power amplifiers has also made a profound impact. This healthy technological competition has no doubt
been to the benefit of both technologies, and the reader should not mistake the proud history of vacuum electronics as an indi-
cation of a technology at its sunset.
+his chapter describes the numerous advances in the area of vacuum electronics, which continue to make the technology the
appropriate choice for many applications. Present-day applications for microwave tubes include satellite and terrestrial com-
munications, industrial and scientific applications from heating materials to heating fusion reactors, and continuing military
applications, such as radar and electronic warfare.
Driven by these continuing needs, this technology area has continued to see impressive advances in recent times, as described
in this chapter.
Chapter 20: Integrated Circuits - by H. Hosack
- Updated information and figures add to this essential chapter.
New information has been added on MEM's and submicron topics.
Chapter 27: Satellite and Space Communications - by G. Hyde
- A discussion of Iridium is included in the chapter. However, Iridium's fate is far from clear.
BSS definition: Broadcast Satellite Services.
DARS definition: Digital Audio Radio System.
ALOHA definition: A made-up name, not an acronym - made up by Prof. Abramson (of the University of Hawaii, of course)
Somebody may have fitted words to the letters, but the author did not hear it defined by Abramson when he lectured on it at
Comsat Labs many years ago.
- Multi-beam antennas of 15 meters diameter for MSS are mentioned at the end of the Spacecrafthtenna section.
Note that 3G wireless is a future system and it is not clear when it will supersede 2.5G, which seems to be growing rapidly.
Chapter 28: Discrete-Time Signal Processing - by K. Jenkins and D. Jones
- The SAW filter data has been updated.
Updated data on antennas.
Advances in Digital signal processing have been presented.
Chapter 36: Radar - by M. Skolnik
- Technological improvements in Surface Acoustic design techniques are covered.
. Information of the newest advances in Radar.
Chapter 32: Antennas - by R. Hansen
Chapter 37: Radio Navigation Systems - by D. Jablonski
The most recent data on GPS.
Information on the remaining uses for LORAN.
Insights into upcoming changes in the field.
Chapter 38: Common Carrier Transmission - by L. Sibley
- Provides good information on DSL.
Chapter 44: Probability and Statistics -by S. Gupta
* Gives concise clear data for design use.
Chapter 46: Cellular TelecommunicationsS ystems - by W. Lee
- Updates on 3G and IMT-2000.
