Five 90-minute sessions. This seminar discusses techniques for identifying the sources of unwanted coupling and radiation, and systematic approaches for their minimization. This course is available as part of the RF Mentor Academy subscription.
Instructor Scott Bullock has prepared a premium tutorial on Automatic Gain Control, Burst or Pulse Jammer Improvement, and Reduce Results as part of a new Electronic Warfare Tutorial Series. This new premium tutorial is now available for all RF Mentor Academy Subscribers. Mr. Bullock worked in research and development for most of his career developing a radar simulator, a spread spectrum microscan receiver, a new spread spectrum receiver where he applied for a patent and was awarded company funds as a new idea project to develop the concept..
Mr. Bullock also developed a spread spectrum environment simulator for a spread spectrum wideband countermeasures receiver using BPSK, QPSK, SQPSK, MSK, frequency hopper, hybrids, AM, FM, voice generator, jammers, and noise. He also designed a high-frequency adaptive filter used to reduce narrowband jammers in a wideband signal; a broadband, highly accurate frequency hop detector; an instantaneous Fourier transform (IFT) receiver; a chopper modulated receiver; a KU-band radio design for burst spread spectrum communications through a troposcatter channel; a Gram-Schmidt orthogonalizer to reduce jammers; an advanced tactical data link; RF analysis of an optical receiver study; a portable wideband communications detector; and an acoustic-optic spectrum analyzer photodiode array controller.
Mr. Bullock holds 18 patents and 22 trade secrets in the areas of spread spectrum wireless data links, adaptive filters, frequency hop detectors, cognitive radios and systems, and wireless telephone and data products. He has published numerous articles dealing with spread spectrum modulation types, multipath, AGCs, PLLs, and adaptive filters. He is the author of two books; Transceiver and System Design for Digital Communications, and Broadband Communications and Home Networking. He is a licensed professional engineer and a member of IEEE and Eta Kappa Nu. He has taught seminars at many different companies for over 10 years. He has taught an advanced communication course at ITT, an engineering course at PIMA Community College, and was a guest lecturer on multiple access systems at PolyTechnic University, Long Island, New York. He is currently an instructor for Besser Associates.
Tutorial topics include:
We are re-organizing material from Rick Fornes' RF Wireless Circuits, Systems and Test Fundamentals course by topic area and making those topics available as individual "lessons" in a new "a la Carte" format. Each lesson includes between 1 - 2 hours of lecture and notes. These are now available to subscribers in the new RF and Wireless a la Carte (178) course.
Available lessons now include:
Other lessons from course 112 to be reorganized into this topic-based format include:
 Five 90-minute sessions. This seminar discusses techniques for identifying the sources of unwanted coupling and radiation, and systematic approaches for their minimization. This course is available as part of the RF Mentor Academy subscription. |
 The need for impedance matching is rooted in basic AC circuit analysis principles. In basic terms, maximum power transfer occurs when the current and voltage are in phase. This workshop examines analytical techniques to design impedance matching networks that deliver the most power possible to an RF load. Q factor and its effect on matching network bandwidth are also described. |
 Three two-hour sessions. Timing-related problems associated with signal sources are one of the major bottlenecks in designing today’s highly complex systems. Over many decades, jitter has been extensively studied and utilized to characterize timing inaccuracies in both digital and analog systems. Conversely, phase noise has been exclusively used in RF systems to represent frequency or phase inaccuracy. For both timing and frequency sensitive systems, phase noise measurement is emerging to be the most accurate method of characterizing all types of signal sources (RF, analog or digital). |
 Learn how to speak engineer…or at least understand them!…and learn at your own pace.… |
 This course presents core concepts essential in understanding RF technology and presents circuit-level designers with the foundation needed to work effectively with high frequency electronics. Participants gain analytical, graphical ( Smith Chart ), and computer-aided techniques to analyze and optimize RF circuits in practical situations. |
 Three two-hour sessions. There are a number of semiconductor technologies being used for power amplifier design. This course introduces students to the GaN transistor, its properties, various structures, discrete and MMIC devices. The properties of GaN will be presented showing the advantage of these devices over other materials for power amplifier applications. |
