3D-ICs bring together multiple silicon dies into a single package that’s significantly larger and complex than traditional systems on a chip (SoCs). There’s no...
Semiconductor manufacturers are under constantly increasing and intense pressure to accelerate innovative new chip designs to market faster than ever in smaller package sizes...
For the past few decades, System-on-Chip (SoC) has been the gold standard for optimizing the performance and cost of electronic systems. Pulling together practically...
The capacity and energy efficiency challenges from the growing appetite for high-speed data along with advanced applications such as LIDAR and quantum computing are...
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
There has been a lot of attention in the news recently about AT&T and Verizon rolling out their first implementations of sub-6GHz 5G radio access networks (RAN). Notably, the FAA and airline industries have voiced serious concerns about potential safety issues for aircraft autopilot and landing systems. As a result of these… Read More
