RF Designer™

The RF Designer™ RF/microwave design app is a highly affordable linear RF and microwave simulator geared towards students, professionals, and hobbyists. What was once only possible on workstations can now be accomplished on your phone or tablet anywhere. Features:
Schematic entryImport 1 through 4 port S-parameter files for use in the schematic.Linear frequency domain analysis of up to 4 ports over user defined frequency range.Export simulated data to S-Parameter files.Plots and graphs: Rectangular, smith chart, and tabular data.Save Smith charts and rectangular graphs to PNG image files.Export tabular and graph trace data to CSV files.
