Something amazing is happening here. In the video below, nesting swallows become trapped in a building when they add doors. The birds soon learn, though, that they can get the doors to automatically open by triggering the motion sensors. This is a story, obviously, of how smart birds are, but here’s what struck me: We often think about human technology as for humans. In this case, however, birds adapted the technology for their own very similar needs (to get in and out).

 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. |
