           ALPHA REPORTS FISCAL 2002 THIRD QUARTER FINANCIAL RESULTS

  Company Meets Previous Financial Guidance, Ramps Production of InGaP Power
         Amplifier Modules and Advances on Plan for Integration with
                         Conexant's Wireless Business

WOBURN, Mass. - January 16, 2002 -- Alpha Industries (Nasdaq: AHAA) today
reported financial results for the fiscal 2002 third quarter ended December
30, 2001.

Net sales for the third quarter of fiscal 2002 were $33.1 million, compared
with $33.0 million in the second quarter of fiscal 2002 and $78.7 million for
the comparable period a year earlier. The adjusted net loss for the third
quarter was $1.9 million, or $0.04 per diluted share, compared with a net loss
of $2.6 million, or $0.06 per share, in the second quarter of fiscal 2002 and
net income of $11.6 million, or $0.26 per diluted share for the third quarter
a year ago. The adjusted net loss for the third quarter of fiscal 2002
excludes transaction costs of $2.1 million for expenses related to Alpha's
previously announced merger with the wireless business of Conexant Systems,
Inc. (Nasdaq: CNXT).

"We are pleased that we achieved our third-quarter financial guidance with a
significant improvement in our bottom-line results," said David Aldrich,
Alpha's president and CEO. "Equally significant, our InGaP HBT power amplifier
module ramp exceeded our expectations. We shipped more than 300,000 power
amplifier modules during the quarter, with yields of greater than 90 percent.
These results rivaled the yields for our mature MESFET and PHEMT products.
Finally, we are moving forward with preparations for integrating Alpha and
Conexant's wireless business."

Alpha/Conexant Merger

On December 17, 2001, Alpha and Conexant announced the signing of a definitive
agreement that will combine Conexant's wireless business with Alpha to create
the pure-play world leader in radio frequency (RF) and complete semiconductor
system solutions for mobile communications applications. Combining the
wireless technology and product portfolios of the two companies will uniquely
position the new entity to drive the evolution of RF integration for all major
air interfaces, including CDMA and GSM, and complete semiconductor and
software solutions for advanced 2.5G and 3G applications.

"As we begin the March quarter, our plans for integrating Alpha and Conexant's
wireless business are moving forward," Aldrich said. "We expect to be prepared
to operate the business as a single combined entity upon closure of the
merger, which we anticipate will take place during the second quarter of
calendar 2002. This merger of two highly complementary wireless businesses
will create a new company that will boast the industry's broadest technology
capability, most complete product offering, and most extensive base of
wireless OEM customers."

Other Recent Highlights

|X| A key InGaP HBT power amplifier design win resulted in production orders
from a top-tier wireless handset OEM for Alpha's newly introduced AP134
module. The new product will be used to provide RF functionality for GSM, PCS
and DCS bands in both standard and GPRS modes on a variety of this customer's
handset platforms. Alpha expects AP134 orders for these platforms to generate
sales in excess of $20 million in calendar 2002. These orders arrived just six
months after Alpha introduced the AP134, and dramatically extend the Company's
penetration into the handset module market.

|X| Alpha increased its penetration of a leading European wireless handset
OEM, receiving multiple orders from this customer and ramping production of
GaAs ICs and other components in volume for multiple new handset platforms.
The phones, which are being sold in the Americas, feature between two and four
Alpha products per handset in the TDMA and CDMA air interface standards. Among
the products ordered were ultra-linear MMIC switches and control circuits
based on multiple-gate PHEMT technology. These ICs handle high power with high
linearity and extremely low insertion loss, and are just one part of the new
generation of low loss, low positive voltage (0 to 2.75V) products based on
Alpha's PHEMT technology. Orders for these platforms are expected to generate
between $5 million and $10 million in sales for Alpha in calendar 2002.

|X| Fueled by growth in the WLAN (wireless local area networking) market,
Alpha began production of its new family of ultra-linear GaAs switches for
802.11b chipsets used in small office, enterprise and home applications. Total
orders for Alpha's high-performance GaAs switches used in WLANs reached 3
million units during the third quarter of fiscal 2002. The increase was driven
by strategic design references with a number of companies including the
industry's leading provider of 802.11b chipsets. In addition, Alpha introduced
a new 5.8 GHz transceiver chipset, featuring a power amplifier, low-noise
amplifier and GaAs switch, for 802.11a applications. Alpha expects to see
accelerating revenue from this market beginning in calendar 2002.

Market Conditions and Alpha's Business Outlook

"The wireless handset business is forecasted to be seasonally slow during the
March quarter," Aldrich said. "In addition, handset sell-through for the
December quarter appears to be coming in lower than the majority of our
customers had anticipated. As a result, current levels of inventory in the
channel are slightly higher than expected. Based on our customer inputs and
channel checks, however, we believe these inventories will be eliminated by
the end of the March quarter. It is also most encouraging to see Alpha's InGaP
HBT power amplifier modules and other new products ramping very successfully
as the March quarter begins."

"Although our visibility into the March quarter is somewhat limited, we expect
that Alpha's new product ramp and gains in market share will enable us to
avoid the seasonal wireless downturn. Therefore, we expect our total net sales
and operating results for the March quarter to be similar to the levels
reported for the December quarter. Furthermore, we will maintain our
aggressive investment in R&D while we continue to manage our cost structure to
position Alpha for growth in subsequent quarters."
