Ralink RT3080, RT3070 802.11n ICs

Ralink Technology Corporation launched two new 802.11n single chips — the RT3080 and RT3070. The RT3080 enables Wi-Fi in handheld/mobile devices and the RT3070 is the industry’s smallest 802.11n USB single chip for PCs, AP/Routers, and client devices. The RT3080 and RT3070 are currently being sampled by early access customers and will be in mass production in the first quarter of 2008.


The RT3070 is a 802.11n USB single chip solution with a tiny 9mmx9mm QFN 76-pin. The RT3070 802.11n solution features high throughput and extended range for single antenna and the reference design kit includes complete, turnkey Wi-Fi solutions including software driver support for Microsoft Windows Vista, XP, 2K, Mac OS X and Linux. 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.


The RT3080 features 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. The chip enables 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.

Ralink’s RT3080 single-chip solution features substantial RBOM integration on the chip, with low noise amplifier (LNA) and power management. The chip has options in FC (Flip Chip) or QFN 76-pin packages to satisfy a wide array of application design requirements such as SIP (System in Package) modules and it is optimized for Bluetooth coexistence. The reference design kit includes complete, turnkey mobile Wi-Fi solutions including software driver support for the Microsoft® Windows® Embedded CE 6.0 enabling ease-of-design and fast time-to-market.

Both the RT3080 and RT3070 single-chip solutions are available in single band frequency (2.4 GHz) and support security with WPA(TM), WPA2(TM), Wi-Fi Protected Set-Up(TM) and QoS (802.11e and WMM) which offer a rich feature set to support voice and video.
