Design RF Signal Chains. Fast.
Build, analyze, and optimize RF signal chains with an interactive web tool. Cascade analysis, touchstone viewing, and link budgets — powered by Rust.
Interactive RF Design
Build signal chains visually, analyze cascade performance in real-time, and inspect touchstone data — all in one tool.
- Create, edit, and organize RF components with realistic parameters — Gain, NF, P1dB, and custom icons.
- Gain, noise figure, and P1dB cascaded in real-time as you build your signal chain.
- Upload .s2p files and overlay S11/S21/S12/S22 parameters on interactive charts.
Built for RF Engineers
Designed by someone who actually uses these tools. Keyboard-first, dark mode, and real export options.
- Navigate with J, 1-5, L, N, S, Escape. Your mouse can take a break.
- Late-night design sessions deserve a UI that doesn't blind you.
- JSON designs, CSV data, PNG plots. Get your data out however you need it.
Everything You Need for RF Design
A focused toolset for signal chain analysis. No bloat, no fluff.
Signal Chain Builder
Visual block lineup editor with drag-and-drop components, inline editing, and unit conversion.
Cascade Analysis
Real-time cascaded gain, noise figure, and P1dB calculations across your entire signal chain.
Touchstone Viewer
Upload and overlay multiple .s2p files with interactive S-parameter charts.
Link Budgets
Full link budget calculations with path loss, antenna gains, and system margin.
Keyboard Navigation
Power-user shortcuts for fast design iteration. J, 1-5, L, N, S — all mapped and ready.
Dark Mode
First-class dark mode that respects your system preference. Because RF engineers work late.
