NOTES TO 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 generally
accepted accounting principles because certain note 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) which 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 bonds with original
maturities of more than 90 days. 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.

SALES. Sales increased 28.9% to $38.6 million for the first quarter of fiscal
2000 from $30.0 million for the first quarter of fiscal 1999. New orders
increased 51.7% to $42.0 million for the first three months of fiscal 2000,
compared with $27.7 million for the same period last year. The increase in sales
and orders was primarily the result of increased demand for wireless products
and our penetration into additional handset platforms. Deliveries to one
customer represented approximately 32% of our total sales for the first three
months of fiscal 2000 compared with 25% for the comparable period last year.

GROSS PROFIT. Gross profit increased 33.4% to $17.1 million or 44.3% of sales
for the first three months of fiscal 2000 from $12.8 million or 42.8% of sales
for the comparable period last year. This increase was primarily a result of
improved operating efficiencies, particularly in Wireless Semiconductors Group,
which continued to leverage capacity and improve yields.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses increased
45.1% to $4.4 million or 11.4% of sales for the first quarter of fiscal 2000
from $3.0 million or 10.1% of sales compared with the same period last year. The
increase in research and development expenses is primarily attributable to the
development of processes and products in the Wireless Semiconductor Products
Group. Over 75% of our total research and development expenses were focused on
the Wireless Semiconductor Products Group's efforts in developing GaAs
integrated circuits and other high volume wireless products.

SELLING AND ADMINISTRATIVE EXPENSES. Selling and administrative expenses totaled
$6.4 million or 16.6% of sales for the first three months of fiscal 2000
compared with $5.5 million or 18.3% of sales for the same period last year. The
increase in selling and administrative expenses reflect increased sales
commissions resulting from higher sales volumes, while the decrease in selling
and administrative expenses as a percentage of sales was attributable to our
continued efforts to control administrative costs.

OTHER INCOME (EXPENSE), NET. Interest expense for the first quarter of fiscal
2000 decreased $32 thousand over the comparable period last year due to a
decline in outstanding borrowings. Interest income for the first quarter ended
June 27, 1999 increased $429 thousand over the comparable period last year as a
result of the higher levels of cash, cash equivalents and short-term
investments.

PROVISION FOR INCOME TAXES. Our effective tax rates for the first three months
of fiscal 2000 and 1999 were 36% and 10% respectively. Last year's rate differed
from statutory rates primarily as a result of the utilization of net operating
loss carryforwards.

improved operating efficiencies, including the leveraging of capacity and
increased manufacturing automation.

FINANCIAL CONDITION

At June 27, 1999, working capital totaled $153.2 million and included $129.6
million in cash, cash equivalents and short-term investments, compared with
$42.7 million of working capital at the end of fiscal 1999. In June 1999, we
completed a public offering of our common stock that raised net proceeds of
$109.4 million. Uses of cash included $5.9 million for capital expenditures as
we continued our investment in the semiconductor GaAs wafer fabrication
operation and the integrated circuit and discrete semiconductor assembly and
test areas, as well as for improved manufacturing capabilities at the ceramics
manufacturing facility.

The $18 million expansion of our GaAs fabrication facility in Massachusetts,
begun fifteen months ago, has allowed us to significantly increase our current
capacity. The new clean room space is complete and in use, and additional
manufacturing equipment is being installed and brought to full productivity as
needed. Demand for our GaAs products continues to increase strongly, and we are
now evaluating the next expansion phase in this fab, which will involve the
addition of new equipment, without the need for additional clean room
construction. We are also examining various options that would allow another
significant expansion of our GaAs capacity, through acquisition or construction.

We believe that our current cash position, together with continued cash
generated from operations and two lines of credit totaling $15 million, will
provide us with adequate funds to support our current operating needs and allow
us to undertake and complete these expansion projects.

NEW ACCOUNTING PRONOUNCEMENTS

SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities"
establishes accounting and reporting standards for derivatives and hedging
activities. It requires that an entity recognize all derivatives as either
assets or liabilities in the balance sheet and measure those instruments at fair
value. SFAS No. 133 will be effective for our fiscal year 2002. We are currently
evaluating SFAS No.133. We do not expect this new statement to have a material
effect on our consolidated financial position, results of operations or cash
flow.

A proposed interpretation of APB Opinion No. 25, "Accounting for Stock Issued
to Employees," would change the way the Company accounts for stock options
issued to non-employee directors. The Company currently uses the intrinsic
value method for such options. The interpretation, if adopted, will require
that we recognize compensation cost, based on the fair value method, for stock
options granted to non-employee directors after December 15, 1998. The portion
of cost recognized would be on a prospective basis from the date of issuance of
the interpretation over the remaining vesting period of the option grant. The
Company is evaluating the potential effect of the interpretation but does not
believe its adoption would have a material effect on our consolidated financial
position, results of operations, or cash flow.

YEAR 2000

The Year 2000 issue relates to the inability of certain computer software
programs to properly recognize and process date sensitive information relative
to the Year 2000 and beyond. To address this issue, we have initiated a
company-wide Year 2000 project under the direction of senior management. We have
evaluated our products and have determined that our products are not date
sensitive. We do not expect Year 2000 exposure for products sold.

We have completed a comprehensive inventory of our internal information systems.
Over the last several years, we have invested in new computer hardware and
software to improve our business operations. All such systems were required to
be Year 2000 compliant as a condition of purchase. We have completed testing of
our critical information systems. As a result of this testing, we do not believe
that any critical systems will cause a significant interruption of our business.
Certain systems require minor upgrades. These upgrades are expected to be
completed by September 1999 and the costs are not expected to be material.

We have also completed a comprehensive inventory of our equipment and
facilities. We have substantially completed testing of critical items to ensure
that they are compliant. As a result of our testing to date, we do not believe
that any critical items will result in a significant disruption to our business.
Minor upgrades are planned for certain items. These upgrades are expected to be
completed by September 1999 and the costs are not expected to be material.

We have completed formal communication with significant suppliers, customers,
financial institutions and other third parties with which we have a material
relationship in order to determine whether those entities have adequate plans in
place to ensure their Year 2000 preparedness. As a result of our communications,
we have not identified any issues with respect to these third parties.

At this time, we have not developed a "worst case" scenario or an overall
contingency plan and do not intend to do so unless, as a result of ongoing
testing and evaluation, we believe these plans are warranted. Based upon our
assessment to date and our expectations that our Year 2000 project will be
substantially complete by September 1999, we believe adequate time will be
available to ensure alternatives can be developed, assessed and implemented, if
necessary, prior to a Year 2000 issue having a negative impact on our
operations. However, we cannot assure that such modifications and conversions,
if required, will be completed on a timely basis.

                                         ---------------------------------------


We have not prepared estimates of costs to remediate Year 2000 problems.
However, based on currently available information, including the results of our
assessment to date, we do not believe that the costs associated with Year 2000
compliance will have a material adverse effect on our business, results of
operations or financial condition.

Although we believe our planning efforts are adequate to address our Year 2000
compliance concerns, we cannot guarantee that we will not experience
unanticipated negative consequences or material costs caused by undetected
errors or defects in the technology used in our internal systems or that third
parties upon which we rely will not experience similar negative consequences.

OTHER MATTERS

Safe Harbor Statement - Except for the historical information contained herein,
this report contains forward-looking statements that constitute the Company's
current intentions, hopes, beliefs, expectations or predictions of the future
which are, therefore, inherently subject to risks and uncertainties. The
Company's actual results could differ materially from those anticipated in the
Company's forward-looking statements based on various factors, including without
limitation: cancellation or deferral of customer orders, dependence on a small
number of large customers, difficulties in the timely development and market
acceptance of new products, market developments that vary from the current
public expectations concerning the growth of wireless communications,
difficulties in manufacturing new or existing products in sufficient quantity or
quality, increased competitive pressures, decreasing selling prices for the
Company's products, or changes in economic conditions. Further information on
factors that could affect the Company's performance is included in the Company's
periodic reports filed with the SEC, including but not limited to the Company's
Form 10-K for the year ended March 28, 1999, and subsequent Forms 10-Q. The

                                     PART I


ITEM 3   QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of changes in the value of a short-term
investment and a financial instrument caused by fluctuations in investment
prices and interest rates.

The Company handles market risks in accordance with established policies. The
Company's risk-management activities include "forward-looking statements" that
involve risk and uncertainties. Actual results could differ materially from
those projected in the forward-looking statements.

Investment Price Risk
The fair value of the Company's short-term investment portfolio at June 27,
1999, approximated carrying value due to its short-term duration. Market risk,
estimated as the potential decrease in fair value resulting from a hypothetical
10% decrease in interest rates for the issues contained in the investment
portfolio, is considered not to be material because of the short-term nature of
the investments.

Interest Rate Risk
The carrying value of the Company's long-term debt, including current
maturities, was approximately $849 thousand at June 27, 1999. Due to the nature
of the debt instruments, management has determined that the fair value was not
materially different from the quarter-end carrying value.


                           PART II - OTHER INFORMATION


ITEM 1    LEGAL PROCEEDINGS


The Company does not have any material pending legal proceedings other than
routine litigation incidental to its business.

The Company has been notified by federal and state environmental agencies of its
potential liability with respect to the Spectron, Inc. Superfund site in Elkton,
Maryland. Several hundred other companies have also been notified about their
potential liability regarding this site. The Company continues to deny that it
has any responsibility with respect to this site other than as a DE MINIMIS
party. Management is of the opinion that the outcome of the aforementioned
environmental matter will not have a material effect on the Company's operations
or financial position.
