The TRF371109 is a highly linear direct-conversion quadrature receiver. The TRF371109 integrates balanced I and Q mixers, LO buffers, and phase splitters to convert an RF signal directly to I and Q baseband. The on-chip programmable gain amplifiers allow adjustment of the output signal level without the need for external variable gain (attenuator) devices. The TRF371109 integrates programmable baseband low-pass filters that attenuate nearby interference, eliminating the need for an external baseband filter.
Housed in a 7-mm × 7-mm VQFN package, the TRF371109 provides the smallest and most integrated receiver solution available for high-performance equipment.

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.
