This workbook from the RF Technology Certification program demonstrates how to convert from dBm to milliwatts using approximation techniques without a calculator. An interactive calculator at the end demonstrates the process with values that you can enter yourself to practice.
This in-depth resource provides comprehensive coverage of femtocells and how they integrate with existing 3G and emerging wireless protocols and standards. Femtocells: Design & Application provides a technical roadmap for migrating to femtocell technology, covering network architecture, media protocols, system performance, and security issues. Detailed architectural diagrams illustrate various deployment options. This is a practical guide to the pioneering technology that enables extended indoor service coverage.
Successfully troubleshooting EMI/EMC problems isn't easy. You need time, you need a strategy, and you need to remain calm. Sometimes, you need a special "sixth sense" that only comes from experience because in some cases, your problems aren't even related with the EUT (equipment under test).
Article by instructor Arturo Mediano about near-field scanners.
I love near field probes because they let me "see" magnetic and electric fields with an oscilloscope or with a spectrum analyzer. They let locate sources of emissions in board, cables, and systems. Near-field scanners also let you see emissions, particularly all over a board. That's hard to do with a single probe.
This webinar will provide an overview of areas 5G will address. We will begin with a sdiscussion 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. Key system parameters will be discussed and the impact of 5G to a Cloud-RAN network architecture will be highlighted.
Arturo Mediano teaches courses on EMC/EMI and Signal Integrity for Besser Associates. He is a frequent contributor to industry magazines and journals on these topics. This article appears in the "Practical Tips" section of InCompliance magazine.
Ferrites for EMI suppression are usually chosen looking for high (resistive) impedance at the frequency of interest; but, sometimes, that ferrite is not working as expected. Perhaps you have saturation effects?
