Microwave and Wireless Synthesizers Theory and Design

Over the past decade, great strides have been made in the technology of microwave oscillators and synthesizers, with digital frequency synthesizers in particular attracting much attention. These synthesizers are now being used in virtually all modern signal generators and radio communication equipment. Until now, however, detailed information about their design has been hard to come by-much of it scattered through journal articles-and most books on the subject have taken a primarily theoretical approach. Enter Microwave and Wireless Synthesizers-the first book to emphasize both practical circuit information from RF to millimeter-wave frequencies and up-to-date theory. Based on course material taught by author Ulrich L. Rohde at George Washington University and recent work done by the author at Compact Software, Inc. and Synergy Microwave Corporation, this volume is a complete revision and update of Rohde's landmark text, Digital PLL Frequency Synthesizers: Theory and Design. While it provides all the necessary theory and formulas, it also offers an in-depth look at the practical side of the phase-lock loop (PLL) in synthesizers-including special loops, loop components, and practical circuits-material that is not available in any other book. Rohde explains loop fundamentals, demonstrates the linear approach to oscillator phase noise, discusses the digital direct synthesizer technique, addresses low noise oscillator design, and provides insight into the role and

Ulrich L. Rohde is President of Compact Software, Inc., in Paterson, New Jersey, a partner of Rohde & Schwarz in Munich, Germany, and Chairman of the Board of Synergy Microwave Corporation in Paterson. Formerly a professor of electrical engineering at George Washington University and the University of Florida, Dr. Rohde, as president of Communication Consulting Corporation, has also consulted on a number of communication projects in industry and government, has published over forty scientific articles in professional journals, and has authored and coauthored several books, including Digital PLL Frequency Synthesizers: Theory and Design, the precursor to this volume.
