Understanding and Measuring Phase Noise
Most every wireless and wireline communication network, along with radar systems uses a digital modulation scheme that is susceptible to noise and jitter. Many systems still use a heterodyne architecture that converts the digital signal to a higher-frequency analog signal. This architecture relies on a mixer to create these higher frequencies. Noise from any component that reaches the mixer can be re-mixed and this reduces the sensitivity and selectivity of the entire system as re-mixed signals leak into adjacent channels. Phase noise is a big contributor to this potential issue.
This eBook provides an overview of phase noise mechanisms, causes and effects, along with insights into how to calculate, measure and design to minimize phase noise. The first article discusses the basics, along with how high-precision quartz oscillators benefit applications. The second article provides an analysis of the causal effects of phase noise in radar and satellite communications. Article three is an application note that provides a thorough analysis of how to measure two-port residual phase noise. The final two articles address design and testing challenges to minimize phase noise in millimeter wave components.
Innovating on 6G with Artificial Intelligence
Today, the 6G standard is in the early phases. Candidate technologies are being researched, prototyped, and simulated to drive the direction of the 3GPP standards development activity. Applying digital twin workflows to simulations and pairing them with a prototype as it moves through the design phase opens up innovative ways to design and identify optimizations early. Modeling software tools that leverage as much real-world data as possible have the potential to solve significant challenges early by incorporating known insights from existing 5G deployments. Research testbeds will be critical to success if 6G aims to spur collaboration alongside innovation. The ability to prototype new AI, digital twin, and software-defined tools across the wireless ecosystem will provide significant results for applying those technologies wisely. This eBook looks at the design densification and test challenges from migrating 5G communications into the 6G sub-Terahertz frequency ranges. Keysight Technologies, the sponsor of this eBook, presents end-to-end capabilities for simulating, testing, and evaluating devices, subsystems, and systems for the evolution of the 5G systems as they evolve towards 6G.
