Front-End IC Boosts Range At 2.4 GHz

Jul 23, 2008 5:24 PM

Model CC2591 is a front-end IC from Texas Instruments that incorporates a robust power amplifier and sensitive low-noise amplifier (LNA) to increase the link budget of 2.4-GHz wireless systems. This "range-extender" works with the company's 2.4-GHz transmitters, transceivers, and wireless systems-on-a-chip to extend the range of low-power wireless systems by as much as 15 times. The CC2591 integrates a power amplifier, low-noise amplifier, balun, switches, inductors and RF-matching network.

The CC2591 provides as much as +22 dBm output power at 2.4 GHz and is suitable for ZigBee and other 2.4-GHz systems in industrial, consumer, and commercial applications. An early adopter of the new chip, Mark Thompson, Development Director for Paxton Access Ltd., notes: "TI's CC2591 provides such an improvement in range and coverage that Paxton Access can, for the first time, offer our customers an alternative to hardwiring their building access control systems. This will significantly reduce system installation costs and allow units to be installed in difficult locations. The CC2591, combined with the CC2430 system-on-chip, has enabled us to develop a new generation of wireless access control systems." The CC2591 is supplied in a 4 x 4 mm QFN-16 package and is supported by the CC2591EMK evaluation module kit.
