New Premium Tutorial: Part 1 of  Integrated Circuits for mmWave Applications

Instructor Ali Darwish has prepared a premium tutorial (part 1 of 3) on Integrated Circuits for mmWave. This new premium tutorial is now available for all RF Mentor Academy Subscribers. 

Ali Darwish, Ph. D., received his Ph.D. degree from Massachusetts Institute of Technology (MIT), Cambridge, MA, in 1996. In 1990, he joined COMSAT Laboratories where he conducted the experimental work on his M. S. thesis. In 1992, he joined the Optics and Quantum Electronics Group, MIT as a research assistant. In 1997, he co-founded Amcom Communications Inc., a leading supplier of high power microwave integrated circuits. At Amcom Communications he served as the vice president of product development where he designed and commercialized several product lines. In May 2003 he joined a US government research lab where he conducted research on wide bandgap materials (GaN), thermal analysis of active devices, and novel MMIC concepts.

Dr. Darwish designed several state-of-the-art monolithic microwave integrated circuits (MMICs) including an X-band low phase noise oscillator, GaN mm-wave power amplifiers, SiGe mm-wave amplifiers, broadband high power amplifiers (in the L-, S-, X-, Ku-, and Ka-band), mixers, digital attenuator, and phase shifters. Dr. Darwish is an associate editor of IEEE Microwave Magazine, an adjunct faculty member with John Hopkins University, and an instructor with Besser Associates. He is an IEEE Senior Member and an active member of MTT-S. His areas of expertise include novel techniques in millimeter-wave MMICs [in GaN and gallium arsenide (GaAs)], sub-terahertz communications, and reliability and thermal characterization of MMICs. He has published over 100 journal and conference papers.

RF and Wireless a la Carte
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:

  • Why Digital?
  • Receiver Criteria
  • Transceiver Architectures and Integration Techniques - New!

Other lessons from course 112 to be reorganized into this topic-based format include:

  • Transmission Lines
  • Smith Chart
  • S-Parameters
  • Matching
  • Low Noise Amplifier Design
  • Smart Phone Architectures
  • RF Power Amplifier Techniques

Now available exclusively to RF Mentor Academy Subscribers! Instructor Doug Morais presents a 90 minute OFDM|5G|NR tutorial.
A series of tutorials in "chalk-talk" format, similar to courses on the popular "Khan Academy" site.1. Signal Flow Graphs  with Rex Frobenius:Signal Flow Graphs allow RF/Microwave circuit designers to use graphical techniques as an alternative to brute-algebraic approaches. By learning four key tools for working with the graphs, the majority of circuit problems can be analyzed. 
This seminar covers the basics of analog and digital modulation, including sampling and pulsed signals. The fundamental digital modulation formats such as BPSK, QPSK, and QAM are described. Continuous-phase formats (MSK, FSK) are covered as well.
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.

Instructor Rick Fornes has trained hundreds of students on dozens of RF and wireless subjects with Besser Associates over the last 20+ years. Now, thanks to the flexibility offered by our Subscription program, we can offer you individual modules from some of Rick's most popular courses in an "a la Carte" format. Some of the modules appear in multiple courses, while others were developed for specific courses with a unique topic focus.
Learn how to speak engineer…or at least understand them!…and learn at your own pace.…
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.
This course provides RF engineers, system designers, manufacturing engineers and other professionals with the essential concepts needed to understand effectively RF and wireless products. This program provides a thorough understanding of RF parameters and as they apply to Wireless applications. At the system level, this course combines theory with real-life examples, providing participants with a complete foundation in understanding architectures - the physical layer requirements and RF measurement techniques.
Instructor Bob Froelich presents a one-hour tutorial webcast on Small Signal Amplifiers.This presentation includes the following topics:Small-Signal ApplicationsSmall-Signal Performance MetricsGainNoise FigureDistortionPower ConsumptionDC BiasIncludes prototype online self study guide
