Mobile WiMAX chip integrates MIMO, PHY and MAC

San Jose, Calif.—GCT Semiconductor has started to sample a Mobile WiMAX 2.5-GHz Wave 2 single chip, the GDM7205, which integrates RF, MAC and PHY, all into one monolithic die.

The GDM7205 is compliant with WiMAX Forum standards and is designed to support portable, nomadic and fixed applications. Based on GCT's CMOS RF technologies, GDM7205 implements MIMO, and all PHY and MAC features required for WiMAX Forum Wave 2 Certification.

According to GCT, the GDM7205 transceiver minimizes the number of external RF front-end components, includes a Mobile WiMAX baseband with high performance dual-processors, and an array of peripherals for connectivity.

The GDM7205 is designed to satisfy the high processing demands of multimedia data processing and wireless connectivity and to increase battery life.

The GDM7205 complies with IEEE 802.16e Mobile WiMAX and WiMAX Forum Wave 2 certification requirements, and supports seamless handover across different cell sectors. The product is provided in a 12-mm x12-mm 289-pin BGA package.

Production is expected in the second quarter of 2008.
