Infineon Technologies AG has launched a new family of single-chip WLAN integrated circuits (ICs)—the XWAY WAVE100—that provides 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 150Mbps 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 lesser 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.
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.
This 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 11Mbps (11b), -76.5dBm at 54Mbps (11g) and -73.5dBm at 150Mbps (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.
