Gallium nitride (GaN) is still considered a relatively new semiconductor technology. Because of its superior properties, it is being used more and more in market areas previously dominated by legacy technologies. One area where GaN rises above the incumbent technologies is thermal management. In short, GaN “can take the heat” much better than other semiconductor technologies. This article and the video titled “Understanding GaN Thermal Analysis” provide practical tips about how to properly design using GaN with thermal considerations in mind.
Gallium Nitride (GaN) technology's ability to support high frequency, wide bandwidths, and high-power density make it invaluable in any market requiring high performance in a small form factor. This article compares GaN to other semiconductor technologies.
Strategy Analytics predicts an explosive growth of emerging 5G networks. They forecasted the number of new base station sectors deployed to double between 2018 and 2024. This rapid 5G growth will result in equipment for nearly 9.4 million new and upgraded wireless base stations deployed by 2024. Many of these 5G base stations will incorporate massive MIMO antennas. These new 5G network architectures incorporating massive MIMO antennas are pushing always-on connectivity to the outer edges of the cellular network. This article covers everything to know about the fundamentals of the RF front-end in the massive MIMO base station.
In this example, various designs of a dual-band antenna constructed from textile fabrics for use in a wearable application are evaluated using XFdtd. When combined in a MIMO array, the antennas show good isolation and acceptable antenna performance.
This article explores options for combining or separating signals and is intended to help engineers determine which component -- or combination of components -- is most advantageous, given the application.
