RF chip provides WiMAX, WiFi connectivity

Las Vegas—GCT Semiconductor has launched what it claims is the market's first single chip that supports Mobile WiMAX IEEE 802.16e WAVE 2 and WiFi 802.11 b/g.

The single-chip GDM7215 integrates mobile WiMAX RF/MAC/PHY and WiFi RF/MAC/PHY on a monolithic die. It supports multimode wireless connectivity with its on-chip RF transceivers, allowing seamless broadband and local wireless roaming. Based on GCT's CMOS RF technology, the GDM7215 integrates WiMAX and WiFi radios, a high performance ARM9 RISC processor along with a 32-bit uniscalar DSP, and a full range of advanced interfaces for network, storage, and audio/visual device applications.

GDM7215 supports all the essential features of mobile WiMAX for the 2 GHz band, including implementation of MISO (two receivers and a single transmitter) and Category-4 H-ARQ (Hybrid automatic repeat-request).

GDM7215 was designed to be an easy (hardware and software) upgrade for GDM7205, which is GCT's WiMAX-only (2.5GHz IEEE 802.16e WAVE 2) single-chip device that was announced in September 2007 and is now in production. For more on the GDM7205, click here.

With proper planning, GDM7215 can fit on the same footprint used for GDM7205 and allow ODMs/OEMs to easily enhance their designs to support WiMAX/WiFi dual operation. GDM7215 also supports 16 bit memory, SDIO and USB2.0 interfaces.

Availability: Samples are now being provided to alpha customers and production will begin in the third quarter of this year.
