DESCRIPTION
CC2591 is a cost-effective and high performance RF
Front End for low-power and low-voltage 2.4-GHz
wireless applications.
CC2591 is a range extender for all existing and future
2.4-GHz low-power RF transceivers, transmitters and
System-on-Chip products from Texas Instruments.
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.
CC2591 provides a small size, high output power RF
design with its 4x4-mm QFN-16 package.
CC2591 contains PA, LNA, switches, RF-matching,
and balun for simple design of high performance
wireless applications.
