The live events I have attended thus far this year have been very good. As much as I liked the virtual events, attending in the comfort of my home or sailboat, it is great to be live and networking inside the semiconductor ecosystem, absolutely.
Ansys has been a great supporter of the Design Automation Conference but this year they … Read More
It was nice to be at a live conference again. DesignCon was held at the Santa Clara Convention Center, my favorite location, which to me there was a back to normal crowd. The sessions I attended were full and the show floor was busy. Masks and vaccinations were not required, maybe that was it. Or there was a pent-up demand to get back engaged… Read More
The electromagnetism problems upon which we spent many hours laboring away on homework in college has a mathematical formulation originally developed by Maxwell, Lorentz, Gauss, Faraday and others. In their full forms, these formulas are partial differential equations that come in many versions – both differential and integral.… Read More
In our previous blog installments, we examined the ingredient for modeling the potential for interference between a 5G C-band base station and an aviation radar altimeter. Using candidate emissions models for the transmitter, wideband susceptibility models for a candidate radar altimeter receiver and antenna and propagation… Read More
In our previous blog installment, we introduced the components of RF interference modeling, and established models for wideband peak emissions of a 5G C-band transmitter and the wideband receiver susceptibility for a radar altimeter receiver. Here, we consider the third component: the wireless channel, which considers the… Read More
In our first blog installment, we outlined the interference concerns surrounding the coexistence of the new C-band 5G telecom service spanning the band from 3.7 to 3.98 GHz with aviation radar altimeters. Radar altimeters are essential components for safety during landing and takeoff, as they offer precise measurements from… Read More
The new 5G C-band service is now up and running in the U.S., and subscribers are finally starting to see some of the promise of 5G. The new C-band services are primarily in spectrum allocations between 3 and 4 GHz, providing the wider channel allocation bandwidths necessary to deliver significantly higher data throughput. At the… Read More
As a pilot and semiconductor professional I was a bit shocked to get an Airworthiness Directive due to the 5G rollout. Airworthiness Directives are legally enforceable regulations issued by the FAA to correct an unsafe condition in a product:
“Airworthiness Directive (AD) 2021-23-12 was issued for all fleets in December… Read More
For 5G to really deliver on its promise of high bandwidth and good coverage, it needs to use an RF band known as C-Band (3.7 to 4.4 GHz). This band is ideal because its frequency is high enough to offer 100MHz wide channels and also low enough that signal attenuation, especially in urban areas, is minimal. In 2020 the FCC auctioned off… Read More
Automatic adaptive meshing in Ansys HFSS is a critical component of its finite element method (FEM) simulation process. Guided by Maxwell’s Equations, it efficiently refines a mesh to deliver a reliable solution, guaranteed. Engineers around the world count on this technology when designing cutting-edge electronic products.… Read More
