概覽
The TRF371109EVM is the evaluation module for the TRF371109 device. The TRF371109 is a direct conversion quadrature demodulator which integrates programmable baseband filters, adjustable DC offset correction, and output buffer amplifiers for driving high speed ADCs. The TRF371109 is suited for operation with WCDMA, CDMA200, WiMAX and LTE modulation as well as with other high bandwidth signal modulation schemes. The TRF371109 is designed to support wireless communications applications that require excellent wideband receiver RF performance (linearity and sensitivity) and flexibility, but with a reduced form factor.

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.
