CC2591RGVTG4

RF Front End (LNA + PA) Overview

The CC2591RGVTG4 is a Texas Instruments RF front-end module designed for 2.4 GHz ISM band applications, specifically supporting IEEE 802.15.4 and Zigbee protocols. It integrates a low-noise amplifier (LNA) and a power amplifier (PA) within a single compact package to enhance link budget performance in wireless sensor networks. The component operates with a supply voltage range of 1.8 V to 3.6 V and features an integrated voltage regulator. It utilizes a 16-pin VQFN (4x4 mm) surface-mount package with exposed thermal pad for efficient heat dissipation.

RF Front End (LNA + PA) Procurement Notes

Verify the RoHS compliance status and lead times directly with authorized distributors, as this component may be subject to end-of-life restrictions or obsolescence notices from the manufacturer. Confirm that the specific suffix matches the required tape-and-reel packaging format for automated assembly processes. Ensure all handling procedures adhere to electrostatic discharge (ESD) protection guidelines during storage and installation.

RF Front End (LNA + PA) Selection Notes

Select this component when a high-gain RF front-end solution is required for 2.4 GHz applications to extend communication range. It is suitable for designs needing integrated amplification without external discrete components. Consider the thermal requirements of the VQFN package and ensure adequate PCB copper area for heat sinking. Verify compatibility with the baseband processor's output power and sensitivity specifications.

RF Front End (LNA + PA) Part Context

This part belongs to the CC2591 family of RF front-ends from Texas Instruments. It is functionally equivalent to the CC2591RGVT but includes the 'G4' suffix indicating lead-free manufacturing and enhanced environmental compliance. It serves as a direct replacement for earlier non-RoHS versions in existing designs requiring updated material specifications.
