TAIPEI, Taiwan—(BUSINESS WIRE)—June 1, 2008— GCT Semiconductor, a leading supplier of mobile WiMAX solutions to the global market, today announced sampling of the industry’s first mobile WiMAX 3.5 GHz Wave 2 single-chip, GDM7213, which includes RF, MAC and PHY, all into one monolithic integrated circuit. GCT continues to build on its leadership position in WiMAX connectivity with this new addition to its state-of-the-art WiMAX product portfolio. Visit GCT this week at WiMAX Expo Taipei, held at the Taipei World Trade Center in Hall 2, Booth C2-3, June 2-6, 2008.

“GCT’s monolithic single-chip WiMAX solutions enable low-power consumption, small form-factor design and low bill of materials cost, all key factors for driving broader WiMAX deployment,” commented Dr. Kyeongho Lee, President and CEO of GCT Semiconductor. “Compliant with WiMAX Forum™ standards, this new solution is ideally suited as the core of WiMAX applications such as USB dongles, data cards (incl. PCI Express), customer premises equipment (CPE) and small modules.”

Based on GCT’s industry-proven CMOS RF technologies, GDM7213 implements MIMO, and all PHY and MAC features required for WiMAX Forum Wave 2 Certification. This compact solution offers a highly integrated, low-power transceiver which minimizes the number of external RF front-end components. It also includes a mobile WiMAX baseband with high performance dual-processors, and an impressive array of peripherals for connectivity.

GDM7213 complies with IEEE 802.16e mobile WiMAX and WiMAX Forum Wave 2 certification requirements, supports seamless handover across different cell sectors and operates over the full 3.4 to 3.7 GHz range. GDM7213 is currently sampling to beta customers. Production is planned for the third quarter of 2008.

GCT’s advanced WiMAX product portfolio also includes GDM7205, the world’s first mobile WiMAX IEEE 802.16e Wave 2-compliant monolithic single-chip; and GDM7215, which offers the functionality of GDM7205 plus WiFi 802.11b/g, all in one monolithic integrated circuit. GDM7205, GDM7213 and GDM7215 are pin-compatible, allowing customers to reuse system design and printed circuit board layout.
