Subscription Exclusive - We are working with Steve Best to come up with some great content on antennas. Dr. Best is preparing a tutorial on Antenna Beamforming for 5G applications. This tutorial will be available to subcribers in late June. [subject to change]
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.
Besser Associates instructor Scott Bullock presents a tutorial webcast on Introduction to Receivers.Topics covered in the webinar include:Parts of the ReceiverImage FrequencyLNA'sMixer Spur AnalysisHigh/Low Level Mixers and IntermodulationPhase NoiseFilters/Group DelayDynamic RangeAGCMinimum Discernible SignalTangential Sensitivity
Last chance - this course will be expiring April 30 2021! 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.
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.

This webinar will provide an overview of areas 5G will address. We will begin with a discussion on the shortcomings of present day cellular systems to highlight the items needing to be addressed in 5G. Provide the overall 5G goals and pillar use cases as defined by ITU. Several deployment options will be provided and summary of the 3GPP scenarios provided.
New This Month Subscription exclusive - 5G/NR/OFDM: Instructor Doug Morais published a new book with Springer last year titled "Key 5G Physical Layer Technologies: Enabling Mobile and Fixed Wireless Access." Based partially on the book, Doug will be presenting a 90 minute tutorial titled
