Solar planes have already traversed the Alps and flown around the world, but one team has its sights set a little higher: the edge of space. SolarStratos is planning to fly a solar-powered plane to an altitude of over 80,000 ft (24,000 m), from where the curvature of the Earth as well as daytime stars will be visible.
The aim of the project is to demonstrate the potential of renewable energy and to explore the possibility of flying people to such altitudes using solar technology.

 Designing Robust 5G Power Amplifiers for the Real WorldSponsored by Keysight Simulating 5G power amplifier (PA) designs at the component and system levels with authentic modulation and high-fidelity behavioral models increases predictability, lowers risk, and shrinks schedules. Simulation software enables multi-technology layout and multi-domain analysis, evaluating the impacts of 5G PA design choices while delivering accurate results in a single virtual workspace. This application note delves into how authentic modulation enhances predictability and performance in 5G millimeter-wave systems. |
