Infineon Technologies AG has announced an 802.11a/b/g dual-band, multimode system and is geared towards meeting the growing requirement of high data rate WLAN systems for enterprise and residential users. The system consists of dual-band, single-chip transceiver, power amplifier (PA) IC, MAC device, and a modem (PHY) IC.

The transceiver operates at 54Mbps in both 2.4GHz and 5GHz frequency bands, and supports the standard extension for 802.11e/i/h. The device also exhibits high sensitivity, transmission mask (for minimum interference), multi-path robustness, and spectrum flatness, the company said.

The PA is a 2.4GHz/5GHz device manufactured using SiGe technology. It integrates the necessary bias circuitry, power control loop components, and standby circuitry to minimize component count in the front-end of the WLAN system.

The MAC device is compliant with the 802.11a/b/g standards and provides the access controller and data management functions on the chipset. It provides interfaces to PC Cards, MiniPCI, PCI, Cardbus, CompactFlash, and USB 1.1.

"The demonstration of our dual-band transceiver represents an important milestone in our WLAN developments," explained Hubert Christl, VP and GM of Local Area Wireless at Infineon Technologies. "Our solution ensures the leading position of our customers in time to market and lowest bill of material by eliminating many external components that are required in other systems."
