GCT Receives Mobile WiMAX™ Certification for its
Single-Chip 2.5 GHz Mobile Subscriber Station Reference Design

GCT's GDM7205K is the first and only monolithic single-chip solution that is WiMAX Forum Certified™

San Jose CA, September 3, 2008 - GCT Semiconductor, a leading supplier of Mobile WiMAX solutions to the global market, today announced that the industry's first Mobile WiMAX 2.5 GHz single-chip, GDM7205K, which integrates RF, MAC and PHY, all into one monolithic integrated circuit, is WiMAX Forum Certified. GDM7205K supports broadband mobile, portable, nomadic and fixed WiMAX™applications.

GDM7205K implements MIMO and all MAC and PHY features. Based on GCT's industry-proven CMOS radio frequency (RF) technology, 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. GDM7205K satisfies the high processing demands of multimedia data processing and wireless connectivity while minimizing power consumption.

"Becoming WiMAX Forum Certified is a great achievement for the industry's first single-chip Mobile WiMAX IC," commented Dr. KH Lee, President and CEO of GCT Semiconductor. "This important milestone makes the GDM7205K design-in decision easier for our customers, knowing that it has received this important third party certification. Our customers can consider this as further evidence that their system designs, based on GDM7205K, are virtually 'plug-and-play', thus enabling the fastest possible time-to-market for their Mobile WiMAX systems."

"The first series of Mobile WiMAX certifications by the WiMAX Forum® represent a critical milestone for the WiMAX industry as it will further accelerate the availability of interoperable solutions and ensure widespread adoption and deployment of WiMAX technology and products," said Ron Resnick, president of the WiMAX Forum. "GCT Semiconductor is playing a key role in taking that important step with the WiMAX Forum, enabling the global WiMAX community to benefit from fully interoperable infrastructures and devices."

GDM7205K is the first and only single-chip reference design to become WiMAX Forum Certified. Independent certification testing was performed by the Telecommunications Technology Association's (TTA) Information Technology (IT) Testing & Certification Lab, a WiMAX Forum designated certification lab. GCT has submitted additional single-chip WiMAX solutions for WiMAX Forum certification. GDM7205K is in production.
