City buses are already the more eco-friendly way of getting around compared to driving in a car. Many cities have begun switching over to hybrid vehicles or alternative fuels in an effort to make transit even more sustainable. And a new bus model might make the change from gas-powered vehicles even easier for city transportation authorities. Proterra’s latest electric bus design can travel 350 miles on a single charge, as WIRED reports.

 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. |
