Touch or Scan above QR to download RFPro Technical Overview
- RFPro optimizes Full 3D and Planar 3D Electromagnetic (EM) simulation for RF circuit designers to automate EM-circuit cosimulation. Design integrity is always preserved without any layout cutting.
- RFPro ensures circuit simulation accuracy by including EM and impedance effects not accounted for by circuit simulators such as from packaging, 3D interconnects, arbitrary metal shapes, antennas, and geometrical process variations.
- RFPro enables you to select which parts of your design to analyze with EM or with circuit simulation. It automatically combines EM and circuit simulation results in ADS, making it possible to interactively tune and optimize geometrical and electrical parameters together for eliminating unexpected hardware iterations downstream.
