About RF View

Last updated 2026-10-13

What RF View is

RF View is an RF analysis application for engineers who work with S-parameters. It opens Touchstone files (.s1p to .s4p), plots them in dB, VSWR, phase, group delay and on a Smith chart, simulates circuits, designs matching networks, converts and batches SNP files, and can control a supported VNA. It runs on Windows 10/11 and Android, and is developed by Gonggan1001.

The basic version is free. Pro is a one-time purchase on each platform: $29.99 on Windows and $3.99 on Android. Windows Pro includes everything in Android Pro plus desktop tools such as VNA control, de-embedding, batch pass/fail analysis and reports. See pricing.

Who writes the guides

The guides and calculators on this site are written by John Shin, Principal Engineer with 25+ years in mobile handset RF design and measurement. The topics come from real handset work: front-end modules (LNA, power amplifier, duplexer, SAW/BAW filter, switch), matching and tuning, S-parameter measurement, de-embedding and debugging. He also builds RF View.

Everything he has written is in the library.

How we work

  • Public data only. Examples use public datasheets, standards and our own sample data. We do not publish employer-confidential or unpublished design information.
  • Formulas are checked. Calculators are tested against known values before they go live.
  • Corrections are welcome. If you find a mistake, contact us and we will fix it and update the article date.
