Overview
The CC2592RGVR is a 2.4 GHz range extender produced by Texas Instruments, designed to enhance the performance of low-power and low-voltage wireless applications. This device is a cost-effective and high-performance RF front end that integrates a power amplifier (PA) and a low-noise amplifier (LNA) to increase the link budget of 2.4 GHz wireless systems. It is specifically tailored to work seamlessly with CC25XX 2.4 GHz low-power RF transceivers, transmitters, and system-on-chip products from Texas Instruments. The CC2592RGVR features a compact 4-mm × 4-mm QFN-16 package, making it ideal for space-constrained designs while providing high-output power and improved receiver sensitivity.
