Edited by John L. Volakis, one of the world's leading authorities in antenna engineering, this trusted resource covers all the classic antenna types plus many new types and designs used in communications systems, satellites, radars, and emerging applications from WLAN to automotive systems to biomedical to smart antennas.
Instructor John Wood has co-authored an article on the history of RF power amplifier linearization strategies. A membership in the IEEE MTT society is required for free access to the article.

Instructor Arturo Mediano has published an article with In Compliance magazine on reducing VHF EMI from a flyback power supply.
Usually, EMC design guidelines in flyback literature are related with the switching effects of the output transistor to minimize emissions for conducted tests in the 9 kHz to 30 MHz range. But failure in radiated emissions in the VHF range is typical when testing the product for EMC compliance.
This app note briefly discusses ten different useful topics related to making VNA measurements.
From the table of contents:
HINT 1. Measuring high-power amplifiers
HINT 2. Compensating for time delay in cable measurements
HINT 3. Improving reflection measurements
HINT 4. Using frequency-offset for mixer, converter and tuner measurements
HINT 5. Increasing the accuracy of noninsertible device measurements
HINT 6. Aliasing in phase or delay format
HINT 7. Quick VNA calibration verification
This app note describes the techniques that can be used to measure devices requiring a high input signal level. Although the steps listed are specific to the E5072 ENA Network Analyzer, the concepts of using a configurable test set apply to other brands and models as well.
Charan Langton has a unique gift for creating tutorials on complex topics that are easy to read and understand. (She has also been known to attend a Besser Associates course from time to time!) She lists recommended books on her Complex to Real website.
Skyworks has a brief animated video describing "how wireless works" for people with no technical background. It does a pretty good job of describing the role of wireless hardware in today's products. It could be useful to help explain your career to those with no idea of what wireless connectivity involves. You might want to bookmark the page before your next family gathering!
