5. MAGIC MARKERS
The classic glass bottle-bodied Magic Marker was first marketed in 1952, and until the early 1990s, the ink formula included a mixture of Toluene and Xylene, two solvents which not only had a distinctive and not unpleasant odor, but which also contained intoxicating properties when inhaled. Today’s permanent markers get their color from less fragrant alcohol-based inks.

 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. |
