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
