Predicting Critical Metrics for Wireless RF Links Featuring Cadence AWR Software 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 for high- performance 5G wireless devices are driving designers to assess critical measurements— noise figure (NF), 1dB gain compression (P1dB), third-order intermodulation (IP3) 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) provide 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.
