High-frequency harmonics produced by modern switched mode power supplies have attracted attention in research community recently. To clarify if these harmonics are indeed a potential power quality concern, a research work has been conducted to understand the propagation characteristics of the harmonics. Through field measurements and computer simulations, the research found that the high-frequency...
The IEEE 519 engineering recommendations is possibly one of the most well known and widely used documents in the power quality area. The objective of the recommendation is, however, many times misunderstood and consequently erroneously interpreted and applied. This panel reviews and discusses common misinterpretations and distortions in the application of harmonic distortion recommendations with particular...
A high intercept points, cost-effective, and power-efficient switching FET double balanced mixer (DBM) is reported. The Switching FET DBM demonstrated in this work offers input intercept points (IIP3) and conversion loss typically 44 dBm and 8.5 dB respectively with 15 dBm LO power for the frequency band (RF: 900-2150 MHz, LO: 850-1950 MHz, IF: 50-200 MHz). The measured interport isolation is typically...
