Component Comparison Workflow
Selecting the best RF component from multiple vendors requires objective, quantitative comparison of S-parameters. RF View's multi-file overlay with Table Marker enables instant side-by-side comparison for any number of files.
Comparison Steps
- Download .s2p files for all competing components from manufacturer websites
- Load all simultaneously in RF View (up to 8 files)
- Select S21 dB view → visual inspection of passband shape and IL
- Table Marker at f₀ → reads S21 for all files simultaneously
- Move marker to stopband → reads rejection for all
- Switch to S11 → compare port match
- Switch to Group Delay → compare GD flatness (critical for 5G/WiFi)
- Export Summary CSV → quantitative comparison table
Decision Matrix Example (LTE Band 3 SAW Filter)
| Vendor | IL (dB) | BW (MHz) | Rejection (dB) | GD Ripple (ns) | S11 (dB) |
|---|---|---|---|---|---|
| Vendor A | 1.8 | 41 | 52 | 85 | −15.2 |
| Vendor B | 2.1 | 39 | 49 | 110 | −13.6 |
| Vendor C | 1.6 | 41 | 55 | 80 | −16.8 |
Vendor C wins on all technical metrics. Cost and availability determine final selection.
