DESCRIPTION  
CC2591 is a cost-effective and high performance RF  
Front End for low-power and low-voltage 2.4-GHz  
wireless applications.  
Integrated Inductors  
Integrated PA  
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.  
Integrated LNA  
Digital Control of LNA Gain by HGM Pin  
100-nA in Power Down (EN = PAEN = 0)  
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.  
Low Transmit Current Consumption  
(100-mA at 3-V for 20-dBm Out, PAE = 33%)  
Low Receive Current Consumption  
CC2591 provides a small size, high output power RF  
design with its 4x4-mm QFN-16 package.  
3.4-mA for High Gain Mode  
1.7-mA for Low Gain Mode  
CC2591 contains PA, LNA, switches, RF-matching,  
and balun for simple design of high performance  
wireless applications.  
4.8-dB LNA Noise Figure, including T/R Switch  
and external antenna match  
RoHS Compliant 4×4-mm QFN-16 Package  
2-V to 3.6-V Operation
