White Paper: Understanding and Correctly Predicting Critical Metrics for Wireless RF Links

AWR published a white paper about correctly predicting cellular, radar, or satellite RF link performance early in the design cycle. The article highlights the advantages of using Visual System Simulator (VSS) RF system simulation software for detailed insight into the full performance of an RF link in next-generation wireless products. The title of the technical paper is: Understanding and Correctly Predicting Critical Metrics for Wireless RF Links.

Understanding and Correctly Predicting Critical Metrics for Wireless RF Links

Understanding and correctly predicting cellular, radar, or satellite RF link performance early in the design cycle has become a key element in product success. The requirements of today’s complex, high performance wireless devices are driving designers to assess critical measurements — noise figure (NF), 1dB gain compression (P1dB), third order intermodulation distortion versus output power (IM3dBc), and signal-to-noise ratio (SNR) — long before manufacturing begins. Traditional modeling methods such as rules of thumb and spreadsheet calculations (Friis equations) give limited insight on the full performance of an RF link in next-generation wireless products. This white paper highlights the advantages of using specialized RF system simulation software to accurately predict critical metrics for wireless RF links.

Using modern software tools to determine system specifications provides much more value than using a spreadsheet as the only method. The software provides for a richer set of models, real word effects accounted for in the calculations, optimization and yield analysis, as well as in-depth spur analysis. Software tools such as VSS give designers much more accuracy and automation in determining system requirements than working exclusively with and maintaining legacy spreadsheets.
