| Matching network design | Auto L/C + microstrip + Real Match | Advanced (noise circles, gain circles) |
| Circuit simulation | Linear cascade (R/L/C + S2P) | Full SPICE + RF nonlinear + EM |
| Electromagnetic simulation | No | Yes (Momentum, AXIEM) |
| Noise figure analysis | S-parameter only | Full noise analysis with noise models |
| Large-signal simulation | No | Yes (Harmonic Balance, LSSP) |
| Filter synthesis (order/ripple) | Basic (BW, IL from S-param) | Full synthesis from specification |
| Platform | Android (free) | Windows/Linux (commercial license) |
| Cost | Free | $10,000–$50,000+ per seat |
| Offline operation | Yes (fully offline) | Yes |
When to Use RF View
- Quick S-parameter inspection without opening a PC
- Field measurements using portable VNA data
- Fast matching network design from measured S-parameters
- Teaching and learning RF concepts
- Component qualification in production environment
- When no EDA license is available
When Desktop EDA Tools Are Needed
- Complex multi-stage amplifier design (gain/noise circles, stability contours)
- Antenna electromagnetic simulation (HFSS, CST, Momentum)
- Harmonic balance (PA efficiency, P1dB, OIP3 simulation)
- Filter synthesis from scratch (specify bandwidth, rejection → get component values)
- System-level link budget with detailed noise and linearity modeling
Best Workflow: Use Both
RF View and desktop EDA tools are complementary. Use desktop EDA for complex design and simulation, then export .s2p results to verify against measurements using RF View in the field or on the bench. RF View's batch processing can analyze thousands of measured .s2p files much faster than opening them one-by-one in ADS.
RF View: Free, fast, mobile RF S-parameter analysis and matching design. Not a replacement for full EDA, but an invaluable companion tool. Free on Google Play.
