NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)


NOTE 1          BASIS OF PRESENTATION

The interim financial information included herein is unaudited. In addition, the
financial information does not include all disclosures required under accounting
principles generally accepted in the United States of America because certain
footnote information included in the Company's annual report to shareholders has
been omitted and such information should be read in conjunction with the prior
year's annual report. However, the financial information reflects all
adjustments (consisting solely of normal recurring adjustments) that are, in the
opinion of management, necessary to a fair statement of the results for the
interim periods. The Company considers the disclosures adequate to make the
information presented not misleading.


NOTE 2          SHORT-TERM INVESTMENTS

The Company's short-term investments are classified as held-to-maturity. These
investments consist primarily of commercial paper and securities issued by
various federal agencies and corporations with original maturities of more than
90 days and less than one year. Such short-term investments are carried at
amortized cost, which approximates fair value, due to the short period of time
to maturity. Gains and losses are included in investment income in the period
they are realized.

NOTE 5          EARNINGS PER SHARE

A reconciliation of the weighted average number of shares outstanding used in
the computation of the basic and diluted (loss) earnings per share for the three
month and nine month periods ended December 30, 2001 and December 31, 2000 is as
follows:

For the periods ended December 30, 2001 and December 31, 2000, options to
purchase approximately 6.6 million and 1.2 million shares, respectively, were
outstanding but not included in the computation of diluted (loss) earnings per
share because their effect would have been antidilutive.

NOTE 6          COMMITMENTS AND CONTINGENCIES

The Company is party to suits and claims arising in the normal course of
business. Management believes these are adequately provided for or will result
in no material additional liability to the Company.

NOTE 7          MERGER WITH CONEXANT SYSTEMS, INC.'S WIRELESS BUSINESS

On December 16, 2001, the Company, Conexant Systems, Inc. (Conexant) and
Washington Sub, Inc., a wholly owned subsidiary of Conexant, entered into a
definitive agreement providing for the combination of Conexant's wireless
business with the Company. Under the terms of the agreement, Conexant will spin
off its wireless business, including its gallium arsenide wafer fabrication
facility located in Newbury Park, California, but excluding certain assets and
liabilities, to be followed immediately by a merger of this wireless business
into the Company with the Company as the surviving company in the merger.
Immediately after the merger, the Company will have approximately 140 million
fully diluted shares outstanding, with current shareholders of the Company
owning approximately 33 percent and current shareholders of Conexant owning
approximately 67 percent of the Company's outstanding shares on a fully diluted
basis.

The merger is to be accounted for as a reverse acquisition whereby Conexant is
treated as the acquirer and Alpha as the acquiree primarily because Conexant
shareholders owned a majority of the combined company as of the announcement
date. Purchase accounting will be performed on Alpha based upon its fair market
value for a reasonable period of time before and after the announcement date of
the merger.

Upon completion of the merger, the Company will purchase Conexant's
semiconductor assembly, module manufacturing and test facility, located in
Mexicali, Mexico, and certain related operations, for $150 million. The Company
will be exploring options for financing this purchase.

The boards of directors of both the Company and Conexant have approved the
definitive agreement. Completion of the proposed merger is subject to
regulatory approvals, receipt of a ruling by the IRS that the Conexant wireless
business spin-off qualifies as tax-free, a Company shareholder vote to
approve the merger, and satisfaction of all other closing conditions. The
proposed merger is expected to be completed in the second quarter of calendar
year 2002.

NET SALES. Net sales decreased 57.9% to $33.1 million for the three months ended
December 30, 2001 from $78.7 million for the same period last year. For the
first nine months of fiscal 2002, net sales decreased 54.8% to $98.3 million
from $217.6 million for the first nine months of fiscal 2001. Orders decreased
66.5% to $25.6 million for the three months ended December 30, 2001, compared
with $76.4 million for the same period last year. The decline in net sales and
orders continues to be the result of a downturn in the wireless handset,
wireless infrastructure and broadband markets. This downturn had a significant
effect on both of our business segments: Semiconductor Products and Ceramic
Products. Deliveries to one customer represented approximately 34% of our total
net sales for the three months ended December 30, 2001 compared to two
customers, which represented approximately 27% and 10%, respectively, of our
total net sales for the same period last year. Deliveries to one customer
represented approximately 32% of our total net sales for the first nine months
of fiscal 2002 compared to two customers, which represented approximately 28%
and 13%, respectively, of our total net sales for the comparable period last
year.

GROSS PROFIT. Gross profit decreased 69.3% to $11.2 million or 33.7% of net
sales for the three months ended December 30, 2001 from $36.4 million or 46.2%
of net sales for the comparable period last year. For the first nine months of
fiscal 2002, gross profit decreased 69.3% to $30.6 million or 31.1% of net sales
compared with $99.6 million or 45.8% of net sales for the same period last year.
This decline continues to be the result of the decrease in net sales and the
resulting underutilization of manufacturing capacity.

                                         Alpha Industries, Inc. and Subsidiaries


RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses increased
0.2% to $9.6 million or 28.9% of net sales for the three months ended December
30, 2001 from $9.5 million or 12.1% of net sales for the comparable period last
year. For the first nine months of fiscal 2002, research and development
expenses increased 11.5% to $29.3 million or 29.8% of net sales from $26.2
million or 12.1% of net sales for the comparable period last year. The increase
in research and development expenses continues to be the result of our
commitment to design new products and processes and address new opportunities to
meet our customers' demands. This sustained effort to meet our customers'
changing product requirements is highlighted by our focus on the migration from
individual chips to integrated radio frequency module solutions.

SELLING AND ADMINISTRATIVE EXPENSES. Selling and administrative expenses
decreased 51.4% to $5.5 million or 16.8% of net sales for the three months ended
December 30, 2001 from $11.4 million or 14.5% of net sales for the comparable
period last year. For the nine months ended December 30, 2001, selling and
administrative expenses decreased $13.8 million to $18.3 million or 18.6% of net
sales from $32.1 million or 14.8% of net sales for the comparable period last
year. The decline in selling and administrative expenses was primarily
attributable to a reduction in workforce, reduced discretionary spending and a
reduction in sales commission expenses.

During the three months and nine months ended December 30, 2001, we incurred
approximately $2.1 million in merger-related expenses associated with our
proposed merger with the wireless business of Conexant Systems, Inc. (Conexant),
which was announced on December 17, 2001. During the nine months ended December
31, 2000, we incurred approximately $1.8 million in expenses associated with our
acquisition of Network Device, Inc. (NDI), which was completed on April 24,
2000.

OTHER INCOME (EXPENSE), NET. Other income, net, for the three months and nine
months ended December 30, 2001 decreased $946,000 and $1.5 million,
respectively, over the comparable periods last year. These decreases were
primarily attributable to a decline in interest income as a result of lower
interest rates.

BENEFIT FOR INCOME TAXES. The benefit for income taxes has been recorded based
on the current estimate of our effective tax rate of 33%. This rate differs from
the statutory federal income tax rate primarily because of state and federal tax
credits. Our effective tax rate for the full fiscal year may be modified based
on future operating results.

the periods indicated. Merger related expenses which, are not related to a

SEMICONDUCTOR PRODUCTS. Net sales for the Semiconductor Products segment
decreased 59.8% to $26.5 million for the three months ended December 30, 2001
from $65.9 million for the same period last year. For the first nine months of
fiscal 2002, net sales for the Semiconductor Products segment decreased 55.8% to
$79.5 million from $179.8 million for the same period last year. The decrease
was primarily attributable to a downturn in both of our targeted markets,
wireless communications and broadband.

Operating (loss) income for the Semiconductor Products segment decreased to an
operating loss of $4.2 million and $16.5 million, respectively, for the three
months and nine months ended December 30, 2001 compared to operating income of
$13.2 million and $34.8 million, respectively, for the comparable periods last
year. The decline was primarily the result of lower revenue, underutilization of
capacity and the continued investment in research and development during the
three months ended December 30, 2001 and first nine months of fiscal 2002 when
compared to the same periods last year.

CERAMIC PRODUCTS. Net sales for the Ceramic Products segment for the three
months ended December 30, 2001 decreased 48.3% to $6.6 million from $12.8
million for the same period last year. For the first nine months of fiscal 2002,
net sales for the Ceramic Products segment decreased 50.1% to $18.9 million from
$37.8 million for the same period last year. The decline was primarily
attributable to a downturn in the wireless infrastructure and broadband markets.

Operating income for the Ceramic Products segment for the three months ended
December 30, 2001 decreased 87.1% to $290,000 from $2.2 million for the same
period last year. For the first nine months of fiscal 2002, operating (loss)
income for the Ceramic Products segment decreased to an operating loss of
$446,000 compared to operating income of $6.5 million for the comparable period
last year. The decline was primarily the result of lower revenue generated
during the three months ended December 30, 2001 and first nine months of fiscal
2002 when compared to the same periods last year.

MERGER-RELATED EXPENSES

During the three months and nine months ended December 30, 2001, we incurred
approximately $2.1 million in merger-related expenses associated with our
proposed merger with Conexant's wireless business, which was announced on
December 17, 2001. During the nine months ended December 31, 2000, we incurred
approximately $1.8 million in expenses associated with our acquisition of NDI,
which was completed on April 24, 2000.

FINANCIAL CONDITION

At December 30, 2001, working capital totaled $166.5 million and included $129.5
million in cash, cash equivalents and short-term investments. Annualized
inventory turns for the nine months ended December 30, 2001 decreased to 8.8,
compared to 9.5 for the comparable period last year. Additionally, days sales
outstanding included in accounts receivable for the nine months ended December
30, 2001 increased to 75 days compared to 66 days for the comparable period last
year. We continued to manage our working capital during the downturn in the
wireless communications and broadband markets. We reduced inventory levels and
managed our investment in capital expenditures, while maintaining our commitment
to investment in research and development and maintaining our manufacturing
capability.

Capital expenditures for the nine months ended December 30, 2001 totaled $32.8
million. Of the $32.8 million, approximately $31.1 million related to the
Semiconductor Products segment as we continued our investment in major capital
initiatives in the semiconductor gallium arsenide (GaAs) wafer fabrication
operation and the integrated circuit (IC) and discrete semiconductor assembly
and test areas. We are creating a GaAs IC production line that will allow the
manufacture of product on six-inch wafers. As of December 30, 2001, we have
spent approximately $25 million on this production line and we expect to
complete this project within twelve months at an estimated cost of approximately
$30 million. Once this new six-inch wafer production line is in operation, we
plan to convert our existing four-inch wafer production areas to six-inch, as
future demand requires. Improvements in manufacturing capabilities at our
ceramics facilities accounted for approximately $1.7 million.

                                         Alpha Industries, Inc. and Subsidiaries


We believe that anticipated cash from operations and available funds, including
the net proceeds from our fiscal 2000 stock offering, will be adequate to fund
our currently planned working capital and capital expenditure requirements, at
least through fiscal 2002.

NEW ACCOUNTING PRONOUNCEMENTS

In July 2001, the Financial Accounting Standards Board (FASB) issued Statements
No. 141, "Business Combinations" (SFAS 141), and No. 142, "Goodwill and Other
Intangibles" (SFAS 142). SFAS 141 requires the use of the purchase method of
accounting and prohibits the use of the pooling-of-interest method of accounting
for business combinations. SFAS 141 also requires that the Company recognize
acquired intangible assets apart from goodwill if the acquired intangible assets
meet certain criteria. SFAS 141 applies to all business combinations initiated
after June 30, 2001 and for purchase business combinations completed on or after
July 1, 2001. The Company has adopted the provisions of SFAS 141.

SFAS 142 requires, among other things, that companies no longer amortize
goodwill, but instead test goodwill for impairment at least annually. In
addition, SFAS 142 requires that the Company identify reporting units for the
purposes of assessing potential future impairments of goodwill, reassess the
useful lives of other existing recognized intangible assets, and cease
amortization of intangible assets with an indefinite useful life. An intangible
asset with an indefinite useful life should be tested for impairment in
accordance with the guidance in SFAS 142. SFAS 142 is required to be applied in
fiscal years beginning after December 15, 2001 to all goodwill and other
intangible assets recognized at that date, regardless of when those assets were
initially recognized.

In October 2001, the FASB issued Statement No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets" (SFAS 144). SFAS 144 supersedes
SFAS 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of" and the accounting and reporting provisions of
Accounting Principles Board Opinion No. 30 for the disposal of a business
segment. SFAS 144 establishes a single accounting model, based on the framework
established in SFAS 121, for long-lived assets to be disposed of by sale. The
Statement also broadens the presentation of discontinued operations to include
disposals of a component of an entity and provides additional implementation
guidance with respect to the classification of assets as held-for-sale and the
calculation of an impairment loss. The Company is required to adopt SFAS 144
effective April 1, 2002. The adoption of SFAS 144 is not expected to have a
material impact on the Company's financial statements.
