PULSE~LINK SELECTS JAZZ SEMICONDUCTOR AS SiGe FOUNDRY PARTNER


SAN DIEGO, Calif., September 15, 2003
 - Pulse~LINK Inc. and Jazz Semiconductor today announced an agreement in which Pulse~LINK will develop a SiGe RF chip for Ultra Wideband (UWB) Wireless Local Area Network (WLAN) communications utilizing Jazz Semiconductor’s advanced silicon germanium (SiGe) Bi-CMOS process. Under the agreement, Jazz will provide foundry services for the RF transceiver chip, the most critical front-end part of Pulse~LINK’s high speed UWB WLAN chipset. Pulse~LINK, a leading developer of Ultra Wideband wireless and wired communication systems, has agreements to supply its chipsets and solutions to customers for highly secure, high performance, next generation WLAN applications.

Pulse~LINK is the only UWB company that has announced a FCC compliant UWB system with 100 meter transmission ranges comparable to WiFi but with significantly higher data rates. The company is also an active voting member in the IEEE 802.15.3a Standards Group for sub 10 meter Ultra Wideband Wireless Personal Area Network (WPAN) technology.

"The added complexity involved in achieving these greater transmission ranges (WLAN vs. WPAN) brings a requirement for greater microchip processing capabilities than might be typically used for other UWB and wireless communications," states John Santhoff, Pulse~LINK founder and CTO. "To mitigate development requirements, we turned to a microchip technology normally reserved for advanced fiber-optics."

Pulse~LINK complements its selection of Jazz with a new team of ASIC engineers that has already commercially developed several successful microchips in the fiber optic industry using the same Jazz SiGe120 process. Bruce Watkins, Pulse~LINK president and CEO adds, "Jazz is a perfect selection for several reasons. Their 0.18µm SiGe120 process with Ft = 150GHz and Fmax = 170GHz is one of the most advanced production processes in the world. The superior performance and integration capabilities of this process shall enable us to develop the most challenging RF transceiver. Furthermore, since the manufacturing is located inside the United States, this relationship complements potential domestic security markets for our technology."

"We are very excited to have been chosen by Pulse~LINK to pursue this technologically challenging project," said Theodore Zhu, VP of Sales, Strategy and Business Development of Jazz Semiconductor. "The market opportunity for Ultra Wide Band applications is significant and the combination of Pulse~LINK’s talented design team and Jazz Semiconductor’s unique process capabilities will help drive the adoption of this technology."
