TRF1108EVM
Overview
The TRF1108 evaluation module (EVM) is used to evaluate the TRF1108 device, which is a differential input to single-ended (D2S) output RF amplifier. The device is designed for applications that require a D2S conversion when driven by a digital-to-analog converter (DAC).
Features
- Operates on single 5V supply
- Differential input signals
- Designed for 100Ω differential input matching
- Power down option available onboard using a jumper connector

Release Information
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.
