Description

CC2591 is a cost-effective and high-performance RF front end for low-power and low-voltage 2.4-GHz

wireless applications. The device is a range extender for all existing and future 2.4-GHz low-power RF

transceivers, transmitters, and System-on-Chip products from TI. CC2591 increases the link budget by

providing a power amplifier for increased output power, and an LNA with low noise figure for improved

receiver sensitivity. The device provides a small size, high output power RF design with its 4-mm × 4-mm

QFN-16 package. The device contains PA, LNA, switches, RF-matching, and balun for simple design of

high-performance wireless applications.
