Alpha Sees Strong Growth in Wireless LAN Markets

Volume Paced by Design References with Leading Provider of 802.11b Chipsets

Woburn, MA. Fueled by the growth of the WLAN (wireless local area networking) market, Alpha Industries, Inc. (NASDAQ: AHAA) today announced that it is experiencing strong order growth for its new family of ultra-linear GaAs (gallium arsenide) switches for 802.11b chipsets used in small office, enterprise and home applications.

In recent months, Alpha has received orders in excess of 3 million units for high-performance ultra-linear GaAs switches used in WLANs. The increase has been driven by strategic design references with a number of companies including the industry s leading provider of 802.11b chipsets. In addition, Alpha has just introduced a new 5.8 GHz transceiver chipset, featuring a power amplifier, low-noise amplifier and GaAs switch, for 802.11a applications.

Our relationship with key players in the 802.11 market positions Alpha to continue gaining share as this business gains momentum, said Liam Griffin, Alpha s Vice President of Sales and Marketing. Recent industry data identifies WLAN for business, small office and home applications as among the communications industry s hottest segments. The orders we are receiving today are in production, and we expect to see accelerating revenue from this market beginning in 2002.

WLANs permit wireless transmission of data between personal computers, laptops and other wireless devices located up to a radius of several hundred feet away. 802.11b has been broadly adopted as the industry standard for WLANs operating in the 2.4 GHz range, in part because it offers seamless interoperability among multiple vendor platforms. The higher frequency 802.11a market targets enterprise and campus environments and provides data rates up to 54 Mbps.

The GaAs RFICs encompassed in these design references are sold into 802.11b access nodes in both PCMCIA and PCI formats used in notebook computers and desktop PCs. The trend of offering embedded wireless LAN capability directly into notebook computers has been a significant catalyst for us, Griffin said. These products provide the mobility and versatility consumers are looking for, delivering low-cost wireless access while maintaining high-speed data rates up to 11 Mbps.
