Ralink Introduces RT3052 and RT3050, the World's First 802.11n Single Chip Access Point/Router SoC with Integrated Ethernet Switch and PHY

HSINCHU, Taiwan—(BUSINESS WIRE)—May 28, 2008— Ralink Technology Corporation, a leading developer of 802.11x chipsets, today announced the industrys first 802.11n single chip AP(Access Point)/routers SoC (System On Chip) with integrated five-port 10/100 Ethernet Switch and PHY. The RT3052 is an 802.11 b/g/n, 2T2R single chip with USB OTG, RGMII, SPI, PCM, I2C and UART interfaces and RT3050 is an 802.11 b/g/n, 1T1R (1 Transmit 1 Receive) single chip with USB interface.

Succeeding Ralinks previous generation of AP/Router intelligent NIC (Network Interface Card) SoC, both RT3052 and RT3050 boast a more powerful MIPS24KEc processor, which enables them to process advanced applications such as Broadband routing, Ethernet to Wi-Fi bridges, VoIP, Online gaming, Home Entertainment and more.

Value Proposition

RT3052 and RT3050 are complete SoC solutions with a high level of integration that accelerates time-to-market and reduce development costs for 802.11n AP/router manufacturers. Ralinks RT3052 2T2R architecture delivers data rates of 300 Mbps and maintains wireless connections over a larger coverage area than other 802.11n solutions. Ralinks RT3050 1T1R architecture is an ideal leverage for manufactures who are looking to replace their 802.11g AP/routers with 802.11n.

Market is demanding smaller form factor and lower BOM cost for the router devices. Increasing the integration level is the only way to meet the requirement, said Frank Lu, IC design manager at Ralink Technology. We are proud to overcome the challenges of heat dissipation and interference among various analog blocks when integrating multiple RF transceivers and Ethernet PHY in the same die.
