GCT Semiconductor announced the world’s first highly integrated single-chip solution, GDM7215, supporting mobile WiMAX (IEEE 802.16e WAVE 2) and Wi-Fi (802.11b/g). GDM7215 implements mobile WiMAX RF/MAC/PHY and Wi-Fi RF/MAC/PHY on a monolithic die.

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

GDM7215 supports multimode wireless connectivity with its on-chip RF transceivers, allowing seamless broadband and local wireless roaming. Based on GCT’s industry-proven CMOS RF technology, the new GDM7215 integrates WiMAX and Wi-Fi 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). It also fully supports Wi-Fi (802.11 b/g) functionality including advanced power management and coexistence support. Due to its optimized design and unique architecture, GDM7215 provides a best-in-class solution for power consumption, size, and multimode Wi-Fi/WiMAX connectivity. The low power consumption and robust coexistence scheme eases development of highly compact modules needed by portable and mobile applications.

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. 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/Wi-Fi dual operation. GDM7215 also supports 16-bit memory, SDIO and USB 2.0 interfaces.
