Press Release

Net sales for the fourth quarter of fiscal 2002 were $28.2 million compared with $33.1 million in the third quarter of 2002 and $54.0 million in the fourth quarter one year earlier. The pro forma net loss for the fourth quarter of fiscal 2002 was $5.5 million, or $0.12 per share, compared with a pro forma net loss of $1.9 million, or $0.04 per share, in the third quarter of fiscal 2002. Net income for the fourth quarter of fiscal 2001 was $3.4 million, or $0.08 per diluted share. As previously announced, Alpha incurred transaction expenses related to the Company's proposed merger with the wireless business of Conexant Systems, Inc. and one-time costs associated with the acquisition of Aimta, Inc. Including these items, Alpha's net loss for the fourth quarter ended March 31, 2002 was $8.5 million, or $0.19 per share.

"We met the revised top-line and bottom-line guidance provided to investors in March," said David Aldrich, Alpha's president and CEO. "As we announced at that time, our fourth-quarter results reflected a decline in wireless infrastructure spending by global telecom carriers, and short-term delays in two power amplifier orders. We expect these orders to begin ramping in the current quarter."

For the 12 months ended March 31, 2002, net sales were $126.5 million compared with net sales of $271.6 million for fiscal year 2001. The net loss before one-time costs and transaction expenses was $13.8 million, or $0.31 per share. Including those items, the net loss was $18.3 million, or $0.42 per share. Alpha reported net income of $33.4 million, or $0.75 per diluted share, for the 12 months ended April 1, 2001.

"While fiscal 2002 was a challenging year for the wireless industry, we continued to increase our investment in research and development," Aldrich said. "That investment has resulted in recent design wins and production orders for our tri- and quad-band power amplifier and RF front-end modules. We also recently received production orders for GaAs switch components from the world's leading Asian mobile phone OEM. As a result, we expect sales to increase in the June quarter as these contracts -- and recent orders for 802.11 wireless data products -- ramp into volume production."

Highlights Alpha's recent news and highlights include:

-- the acquisition of Aimta, Inc., a developer of Low Temperature Co-fired Ceramics (LTCC), a platform for packaging and integrating multi-chip modules. Acquiring Aimta's technology enables Alpha to offer original equipment manufacturers (OEMs), a module that combines power amplification with front-end switching and filtering capability;

-- design wins for switch-filter modules incorporating Alpha's LTCC technology. These include a module that has been designed into a combination CDMA wireless handset/GPS receiver and modules for 802.11 WLAN chipsets;

-- recent orders for Alpha's quad-band InGaP power amplifier modules, which have been designed into two new handsets being introduced in 2002 by the Company's largest wireless handset customer. The customer is integrating Alpha's 137-501 module into GSM/GPRS phones being launched in the United States, Europe and Asia;

-- volume production shipments of GaAs ICs to Asia's leading wireless handset OEM for a high volume CDMA mobile phone; and

-- production orders for Alpha's new transmit chain module incorporating a dual-band HBT power amplifier, PA controller, MMIC switch, filter, directional detector, switch controller and discrete semiconductors.

Merger Agreement with Conexant Wireless Business

Alpha's proposed merger with the wireless business of Conexant Systems, Inc. reached an important milestone in the fourth quarter when the Federal Trade Commission granted early termination of the anti-trust waiting period under the Hart-Scott-Rodino Antitrust Improvements Act. Within the next few weeks, Alpha expects to finalize its proxy statement to shareholders relating to the special meeting of shareholders to consider the merger. Subject to shareholder approval and satisfaction of other closing conditions, the Company expects the merger to close in the June quarter.

"Our integration plan is progressing on schedule," Aldrich said. "More than 100 people are involved in the integration process, reviewing all aspects of our investment strategy, sales channel, operations and organization structure. Based on the strength of our combined product portfolio and customer relationships, we are confident that we can generate significant customer, product and sales synergies. In addition, we have developed and are preparing to implement detailed plans to achieve profitability by accelerating top-line growth and reducing costs. We look forward to providing additional details about our strategic direction, operating plans and financial model in the near future."

Business Outlook -- Sequential Growth

"Based on the strength of our production orders and design wins, we expect Alpha's first quarter fiscal 2003 revenues to improve between 8 and 12 percent sequentially," Aldrich said. "We expect to see that growth come from our new modules, where we capture between $2 and $5 of total content per phone, and our switch business, where we remain a clear market leader. On the operations side, we anticipate our gross margin will improve by between 400 and 460 basis points, resulting in a loss per share in the fiscal 2003 first quarter, excluding merger-related expenses, of $0.09 to $0.10."
