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
