Ottawa, Canada, 6 May 2002

k0511si - SiGe Semiconductor's range charger technology boosts performance of class 1 bluetooth products from W-Link.

RangeCharger(TM)-based PA2423MB power amplifier drives Class 1 Bluetooth(TM) products from W-Link. The PA2423 power amplifier strengthens signal integrity in W-Link's Bluetooth products to boost performance of wireless data exchange, and network and Internet access in a range of personal wireless, SOHO and Enterprise applications.

W-Link's Class 1 Bluetooth products, including network gateways, access points, Compact Flash and PCMCIA cards, USB dongles, and embedded modules, are expected to be shipping in volume by June 2002. "Our collaboration with W-Link represents a substantial business opportunity," said Jim Derbyshire, president and CEO, SiGe Semiconductor. "W-Link's products are gaining recognition across the Bluetooth market, since they achieve consumer expectations for performance and transmission range. The combination of our RF technology with W-Link's manufacturing and distribution channels allows us to quickly deliver products to end consumers and take full advantage of this growing market demand."

Portfolio delivers complete range of wireless connectivity options SiGe's PA2423MB is integrated into six of W-Link's Class 1 Bluetooth products, including the WBT-3041 Compact Flash card for PDAs, handhelds, and laptops; the WBT-3021 USB dongle and WBT-3031 PCMCIA Card for laptops and personal computers; the WBT-3051 Bluetooth Gateway and WBT-3052 Bluetooth Access Point for network and Internet access; and the WBT-3011 Class 1 module for embedded applications.

W-Link's Class 1 Bluetooth products pair SiGe's PA2423MB power amplifier with transceiver/baseband chips from all major Bluetooth chipset companies, ensuring that consumer expectations are met for high performance, low power consumption, small size and ease of use. SiGe's PA2423MB contributes to these benefits, based on a highly efficient silicon germanium architecture that enables extremely low current consumption and high integration. This allows designers to easily support targets for longer battery life and small form factor. The silicon germanium structure also ensures high performance and stability.

Able to deliver +22.5 dBm output power with 45 percent power-added efficiency, the PA2423MB overcomes antenna and filter losses to ensure high data integrity over the specified transmission range. Using SiGe's PA2423MB, W-Link's Class 1 Bluetooth products enable high-quality wireless communications over a range of 50 meters. "SiGe has been an ideal partner, since their power amplifiers are easy to implement, and add to the real-world performance and range of our products," said Dr John Chow, president, W-Link. "We anticipate extending our relationship with SiGe as we progress to deliver these same benefits to other short-range wireless applications, including 802.11b WLAN."
