Single-Chip Dual-Band Combo Device Supporting 802.11n, Bluetooth 4.0+HS & FM Receiver
Product Code: BCM4334
This single-chip dual-band combo chip provides a complete wireless connectivity system with ultra-low power consumption for mass-market smartphones.
Using advanced design techniques and 40 nm process technology to reduce active and idle power, the BCM4334 is designed to address the needs of highly mobile devices that require minimal power consumption and compact size while delivering dual-band Wi-Fi connectivity. The chip includes IEEE 802.11 a/b/g/n single-stream MAC/baseband/radio, Bluetooth 4.0 + HS and an integrated FM radio receiver. It is designed to be used with external 2.4 GHz and 5 GHz front-end modules, which include power amplifiers, T/R switches and optional low-noise amplifiers. The combo device also features advanced switching techniques that enable concurrent dual-band operation to simultaneously support network connectivity with one band while also allowing content streaming via technologies such as Wi-Fi Display™ and Wi-Fi Direct™. The advanced architecture supports the latest "always on always connected" (AOAC) applications such as push e-mail or Internet radio services, even while the host smartphone is in sleep mode, further preserving battery life. The BCM4334 also includes a power management unit, which simplifies the system power topology and allows for operation directly from a mobile platform battery while maximizing battery life.
