Overview
The CC2590RGVRG4, produced by Texas Instruments, is a high-performance RF Front End designed for low-power and low-voltage 2.4-GHz wireless applications. This component is a cost-effective range extender for all existing and future 2.4-GHz low-power RF transceivers, transmitters, and System-on-Chip products from Texas Instruments. It enhances the link budget by providing a power amplifier for increased output power and a low-noise amplifier (LNA) for improved receiver sensitivity. The CC2590 is packaged in a compact 4x4-mm QFN-16 package, making it ideal for high-output power RF designs in a small footprint.
