Infineon Introduces Energy Efficient Single-Chip XWAY WAVE100 Family for Low-Cost 802.11n WLAN Home Gateways


Neubiberg, Germany – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) today introduced a new family of single-chip WLAN integrated circuits (ICs). The new XWAY™ WAVE100 ICs provide a high-performance and cost-effective solution for wireless network access points that are compliant to the 802.11n draft standard for data rates up to 150Mbit/s as well as the 802.11 b/g standard. The XWAY WAVE100 family lowers the total system cost for home gateway manufacturers, with a significantly reduced RBOM (Rest of Bill-of-Material) and improved manufacturing throughput. Additionally, it is fully compliant to the European Union Code of Conduct (CoC) for broadband equipment energy efficiency.

The single-chip XWAY WAVE100 family integrates the WLAN Baseband, Media Access Controller (MAC), RF, Low Noise Amplifier (LNA) and Power Amplifier (PA) functionalities. Systems based on the XWAY WAVE100 family require the industry’s lowest number of external components and need no external memory. This results in a RBOM which is about 25 percent lower than existing solutions in the market and up to 70 percent smaller board-space.

In the manufacturing of WLAN equipment, the production throughput largely depends on the trimming of the WLAN device to achieve optimum performance. Trimming adjusts for the characteristics of analog components which vary with the silicon process, temperature and life-time. With the XWAY WAVE100 family, Infineon provides an innovative integrated tool-box to support on-the-fly trimming with temperature, voltage and supply monitoring during standard operation mode. This provides savings on expensive RF test equipment, in many cases makes external trimming during manufacturing unnecessary, and minimizes calibration time during manufacturing.

“With the new XWAY WAVE100 family, Infineon enables customers to meet growing consumer demand for high-speed wireless connectivity by offering WLAN 802.11n 1x1 with up to four times more speed than earlier generation WLANs at the price of legacy 802.11b/g systems,” said Christian Wolff, President of the Wireline Communications Division at Infineon Technologies. “By combining our system know-how with expertise in chip design, we focus on product innovations to reduce the total system manufacturing cost for our customers.”

About XWAY™ WAVE100

The XWAY WAVE100 single-chips are available with either SDIO or PCI interface. When used in combination with the XWAY AMAZON-SE and XWAY ARX182 ADSL2+ single-chips for low-cost xDSL WLAN router and Gateway respectively, the SDIO variant frees up the USB 2.0 Host interface of the xDSL single-chips for other tasks such as connecting a hard disk, printer or 3G dongle. The PCI variant can be used in combination with XWAY ARX100 family for full-featured WLAN gateways.

The XWAY WAVE100 family features advanced power management modes to reduce the power consumption by at least 25 percent compared to existing 802.11n solutions in the market. Different power modes including sleep and diverse power-down states are implemented. Infineon again sets a benchmark in energy efficiency by enabling customers to create green designs which exceed the requirements of the European Union CoC on energy consumption of broadband equipment.

This new solution achieves best RF performance with output power at least 2dBm higher than available solutions in the market, best-in-class sensitivity of -90.5dBm at 11Mbit/s (11b), -76.5dBm at 54Mbit/s (11g) and -73.5dBm at 150Mbit/s (11n 1x1). Furthermore antenna diversity is supported to improve receiver sensitivity. The XWAY WAVE100 family uses only a single 3.3V supply, operates at 2.4GHz and supports both 20MHz and 40MHz bandwidths.


Samples of the XWAY WAVE100 in a PG-VQFN-108 package are available with mass production starting in Q4 2009. Reference designs together with Infineon’s xDSL single-chips are also available.

Infineon will be presenting its XWAY WAVE100 family and other product innovations at booth #245 at the Broadband World Forum in Paris CNIT, September 7-9, 2009.
