The RT307X series is a highly integrated MAC/BBP and 2.4G RF single

chip supporting 150Mbps to 300Mbps throughput. It fully complies

with IEEE 802.11n draft 4.0 and IEEE 802.11 b/g standards, delivers

reliable, cost-e�ective, feature rich wireless connectivity at high

throughput from an extended distance. Optimized RF architecture

and baseband algorithms provide superb performance with low

power consumption. The intelligent MAC design deploys a highly

e�cent USB engine and hardware data processing accelerators

without overloading the host processor. The RT307X is designed to

support basic features related to security, quality of service and

international regulation, giving the end user the greatest

performance any time, and in any circumstance. The RT307X enables

the entire 802.11n WLAN solution to �t on a tiny USB module design,

creating the ideal choice for next generation Consumer Electronic,

Broadband and PC Desktop WLAN solutions.
