Overview
The RF Cascade Calculator is a web-based tool for performing RF signal chain (lineup) cascade analysis. It computes cascaded performance parameters across a multi-stage RF signal chain using standard cascade equations (Friis formula for noise figure, reciprocal power sums for IP3/IP2/P1dB, etc.).
The tool is hosted on the TI Developer Gallery and runs entirely in the user's browser — no software download or installation is required.
