Modular RF signal chain simulator with real-time spectrum display
Design a cascade of RF components and probe any node to see the spectrum.
- 🔧 Modular components — Amplifiers, attenuators, mixers, filters, splitters, combiners, and more
- 📊 Real-time spectrum display — Probe any node in the signal chain with ImPlot
- 📐 S-parameter support — Touchstone file import for accurate component modeling
- 🧮 DSP pipeline — Polyphase filter bank channelizer, noise PSD analysis
- 🏗️ Dirty-flag caching — Efficient recomputation only when parameters change
- 🧩 Extensible architecture — Clean engine+widget pattern for adding new components
# Clone and build
