Designing Robust 5G Power Amplifiers for the Real World

Sponsored 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.

Secure Authentication ICs for Disposable and Accessory Ecosystems

Sponsored by Mouser Electronics and Microchip

Secure authentication for disposable and accessory ecosystems is a critical element for many embedded systems today. In this episode of Chalk Talk, Amelia Dalton and Xavier Bignalet from Microchip discuss the benefits of Microchip’s Trust Platform design suite and how it can provide the security you need for your next embedded design. They investigate the value of symmetric authentication and asymmetric authentication and the roles that parasitic power and package size play in these kinds of designs.
