The TRF1218 is a very high performance, single-ended to differential radio frequency (RF) amplifier optimized for wide signal bandwidth applications. The device is excellent for ac-coupled uses that require a single-ended to differential conversion such as driving an RF sampling analog-to-digital converter (ADC). The device combines the functionality of a wide-band gain block and wide-band passive balun in a single 2mm × 2mm package. The on-chip matching components simplify printed circuit board (PCB) implementation and enables high performance over the full operating bandwidth. The device is fabricated in Texas Instruments’ advanced complementary BiCMOS process and is available in a space-saving WQFN-FCRLF package.
The TRF1218 operates on a single-rail supply and consumes about 190mA of active current. A power-down feature via a single pin is also available for simplified power savings.

TI RF cascade calculator
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.
