Ralink Launches Two 802.11n Single Chips

(Product News, 3 Jan 2008)

Ralink Technology Corp. has released two new 802.11n single chips—the RT3080, which enables Wi-Fi in handheld/mobile devices, and the RT3070, an 802.11n USB single chip for PCs, AP/Routers and client devices.

The RT3080 boasts on-chip gain selectable LNA with optimized noise figure for high sensitivity, on-chip LDO regulators that supply a single battery in SDIO mode and reduce power consumption by supporting adaptive transmit output power and power amplifier bias control. The chip draws only 300mW power at full speed receiving mode. These key features facilitate efficient Wi-Fi enabled mobile devices and for the first time, a mobile device is now available with a power level and price point that can drive the mass adoption of Wi-Fi in personal media players, smart phones, digital still cameras, gaming and other portable consumer devices.

The RT3070 is claimed to be the industry's smallest 802.11n USB single chip, available in a 9x9mm QFN 76-pin package. The high integration and low-cost digital CMOS design makes this chip ideal for the next generation of consumer electronics, broadband and PC desktop WLAN solutions.
