Combo chip brings 802.11n to handsets

Integrating 802.11n Wi-Fi, Bluetooth, and FM technologies on a single silicon die, the BCM4329 provides up to 50 Mbits/s of actual wireless throughput — bringing wireless speeds up to two times faster than that of the 802.11g available on handsets and other mobile devices today. The chip employs space-time block coding (STBC), an 802.11n feature that enables a mobile device to maintain a connection with an access point anywhere within an expanded coverage area.

The chip integrates 2.4- and 5-GHz CMOS power amplifiers. Since Bluetooth and Wi-Fi operate in the same 2.4-GHz band, the BCM4329 use innovative coexistence algorithms and a shared antenna system to minimize interference (Less than $10 — samples available now.)
