When the Japanese town of Susami in the Nishimuro district of the Wayakama Prefecture, decided that they wanted to have more tourism, Toshihiko Matsumoto, the postmaster came up with the unique idea of putting a mailbox underwater. This mailbox currently in use, but it does require the purchase of waterproof cards and oil based pens. Once the postcard is written all the sender has to do is dive down and insert it into the mailbox at the ocean floor for later pickup. via Laughing Squid
 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. |
