GCT Semiconductor to demonstrate wireless streaming audio at COMDEX based upon its direct conversion RF

Display Shows the Benefits of CMOS-Based Bluetooth Products and Patented RF Architecture

LAS VEGAS, NEVADA - Nov. 12, 2001 - GCT Semiconductor, a fabless semiconductor company serving the wireless device industry, today announced that the company will be hosting demonstrations of a streaming audio application using the Bluetooth standard at the Fall COMDEX show to be held at the Las Vegas Convention Center from Nov. 12-16, 2001.

The demonstration will link a laptop playing an MP3 audio loop to a set of speakers and headphones up to 30 feet away featuring GCT's new Bluetooth-enabled products at each end. These products are based upon the company's proprietary direct conversion RF technology, which can also be applied to support other wireless communication standards.

All demonstrations will take place in meeting room LN 222 on the second floor of the Las Vegas Convention Center.

"This display is a compelling demonstration of the capabilities of GCT's Bluetooth chipset solution, which relies on our patented direct conversion RF technology and high yielding CMOS processes," said Dr. K.H. Lee, co-founder and chief executive officer at GCT.

"Our Bluetooth baseband processor includes an embedded DSP for MP3 decoding, and along with our radio, displays the kind of innovative, cost-effective solutions that GCT is bringing to the wireless device marketplace."

The streaming audio demonstration consists of a wireless point-to-point network, which includes a laptop and two of GCT's new Bluetooth evaluation boards. The piconet master features an evaluation board housing GCT's GDM1000 Bluetooth Radio and GDM1201 Bluetooth baseband processor, which are connected to a laptop via a USB interface and configured via a Host Controller Interface.

The piconet slave point consists of a second evaluation board, which includes an additional Bluetooth radio and GCT's GDM1202 Bluetooth baseband processor. The baseband, which features an embedded DSP for MP3 decoding, is targeted for wireless MP3 players, headsets and speaker applications.

Through the use of the chipsets' embedded protocol stacks and the MP3 profile that is defined in the Bluetooth standard, the demonstration will show how continuously streaming audio data can be sent within a wireless network.

GCT is focused on developing integrated, cost-effective semiconductor solutions for wireless devices on CMOS that leverage the benefits of its patented direct conversion architecture. Current products include Phase Locked Loop (PLL) chips for wireless handsets, a two-chip Bluetooth chipset and a one-chip Bluetooth solution.

The company's GDM1000 transceiver has a GFSK modem designed to work with either of the baseband ICs used in its COMDEX demonstration.
