Press Release

WOBURN, Mass., Apr 9, 2002 (BUSINESS WIRE) -- Alpha (Nasdaq: AHAA) today announced that its quad-band InGaP HBT power amplifier module has been designed into two new-generation mobile phones scheduled to be introduced in 2002 by a top-tier wireless handset OEM.

Alpha's 137-501 module will be integrated into dual-band, GPRS compatible handsets that are expected to be introduced in the United States, Europe and Asia in the second half of 2002. The module features Alpha's proprietary silicon bipolar logic controller in a fully integrated 50-Ohm input/output package. The state-of-the-art functionality of the module effectively eliminates the need for more than two dozen matching components.

"Our InGaP HBT power amplifier module is a compelling solution that offers the OEM a unique level of flexibility," said Colin Sweeney, Alpha's general manager of power amplifier products. "Because it supports the world's most widely used wireless frequencies, the module can be used to power quad-band wireless handsets as well as dual- and tri-band phones. This flexibility allows OEMs to streamline their inventory and more easily manage logistics."
