RF Signal Chain Design Platform

SigChain

Documentation

◈
Design Visually

Build signal chains on an interactive canvas. Add components using natural language or direct editing.

▣
Analyze Instantly

Cascade analysis runs automatically. Gain, NF, OIP3, OP1dB, sensitivity, and SFDR update in real time as you modify the chain.

⊕
Iterate Rapidly

Save and compare chains. Upload and link parts. Utilize the built-in AI assistant to quicken development.

Key Capabilities

  • Cascade analysis: gain, NF, OIP3, OP1dB, P1dB
  • 20+ components: LNA, PA, mixer, VGA, filters, and more
  • Friis NF cascade and recursive OIP3 computation
  • TX metrics: PA drive, output power, compression headroom
  • RX metrics: sensitivity and SFDR
  • Frequency planning: RF, IF, and LO band specification
  • Parameter provenance tracking (user / datasheet / AI / derived)
  • Version history and named snapshots
  • Component library with datasheet PDF import
  • AI assistant for chain construction and parameter setting

Grounded in RF Engineering Principles

Every component is a node in a directed graph. Every connection carries a signal. The tool computes what a cascade spreadsheet would — but interactively, with provenance-tracked parameters, AI assistance, and version history.
