NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)

NOTE 1  BASIS OF PRESENTATION

The interim financial information included here 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
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) 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. 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
months ended July 1, 2001 and July 2, 2000 is as follows:



                                                                           JULY 1,         JULY 2,

For the quarters ended July 1, 2001 and July 2, 2000, options to purchase
approximately 6.7 million and 31,000 shares, respectively, were outstanding but
not included in the computation of diluted 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 significant additional liability to the Company.

NET SALES. Net sales decreased 50.9% to $32.2 million for the first quarter of
fiscal 2002 from $65.7 million for the first quarter of fiscal 2001. Orders
decreased 67.1% to $23.7 million for the first quarter of fiscal 2002, compared
with $72.2 million for the same period last year. A downturn in the wireless and
broadband markets resulted in lower sales during the first quarter of fiscal
2002 in both of our business segments- Semiconductor Products and Ceramic
Products- when compared to the first quarter of fiscal 2001. Deliveries to one
customer and one value-added distributor represented approximately 22% and 13%,
respectively, of our total net sales for the first three months of fiscal 2002.
Deliveries to two customers represented approximately 32% and 14%, respectively,
of our total net sales for the first quarter of fiscal 2001.

GROSS PROFIT. Gross profit decreased 70.2% to $8.8 million or 27.3% of net sales
for the first quarter of fiscal 2002 from $29.5 million or 45.0% of net sales
for the comparable period last year. This decrease was primarily due to the
decline in sales and the resulting underutilization of manufacturing capacity.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses increased
24.2% to $9.8 million or 30.4% of net sales for the first quarter of fiscal 2002
from $7.9 million or 12.0% of net sales for the comparable period last year. The
increase in research and development expenses was primarily the result of our
continued commitment to meeting our customers' changing product requirements,
including the migration from individual chips to integrated radio frequency
module solutions. During the first quarter ended July 1, 2001, we announced the
introduction of the world's first tri-band power amplifier module employing
InGap HBT (indium gallium phosphide heterojunction bipolar transistor) process
technology. This module is designed for use in existing dual-mode wireless
handsets and is fully GPRS (General Packet Radio Service) compliant.

SELLING AND ADMINISTRATIVE EXPENSES. Selling and administrative expenses
decreased 42.6% to $6.7 million or 20.8% of net sales for the first quarter of
fiscal 2002 from $11.7 million or 17.8% of net sales for the first quarter of
fiscal 2001. The decrease in selling and administrative expenses was primarily
the result of a reduction in sales commission expenses due to lower sales levels
and to specific actions taken to reduce costs, including a reduction in
workforce and modification of employee work schedules, as well as management of
discretionary spending.

OTHER INCOME (EXPENSE), NET. Other income, net, for the first quarter of fiscal
2002 remained consistent at approximately $1.9 million when compared to the
first quarter of fiscal 2001. Other income, net, consists primarily of interest
income generated by our cash, cash equivalents and short-term investments.

CREDIT FOR INCOME TAXES. The credit 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.

SEMICONDUCTOR PRODUCTS. Net sales for the Semiconductor Products segment
decreased 50.6% to $26.2 million for the first quarter of fiscal 2002 from $53.0
million for the same quarter last year. The decrease was primarily attributable
to a downturn experienced in both of our targeted markets, wireless
communications and broadband, during the first quarter of fiscal 2002.

Operating (loss) income for the Semiconductor Products segment decreased to an
operating loss of $7.0 million for the first quarter of fiscal 2002 compared to
an operating income of $7.9 million for the same quarter last year. The decline
was primarily the result of the impact of relatively fixed operating costs
against lower revenue during the quarter ended July 1, 2001.

CERAMIC PRODUCTS. Net sales for the Ceramic Products segment decreased 52.6% to
$6.0 million for the first quarter of fiscal 2002 from $12.7 million for the
same quarter last year. The decrease was primarily attributable to a downturn in
the wireless infrastructure and broadband markets during the first quarter of
fiscal 2002.

Operating (loss) income for the Ceramic Products segment decreased to an
operating loss of $719,000 for the first quarter of fiscal 2002 compared to an
operating income of $2.1 million for the same quarter last year. The decline was
primarily due to lower revenue generated during the quarter ended July 1, 2001.

FINANCIAL CONDITION

At July 1, 2001, working capital totaled $185.3 million, including $149.6
million in cash, cash equivalents and short-term investments. Annualized
inventory turns for the first quarter ended July 1, 2001 decreased to 7.1
compared to 10.2 for the same period last year. Additionally, days sales
outstanding for the first quarter ended July 1, 2001 increased to 67 days
compared to 62 days for the same period last year. During this quarter, we
continued to manage our working capital. Responding to the downturn in the
wireless communications and broadband

markets, we delayed investment in certain capital expenditures and reduced our
inventory levels, therefore minimizing our exposure to inventory obsolescence.
We accomplished this while maintaining our commitment to investment in research
and development and maintaining our manufacturing capability. Cash provided by
operations for the quarter was $709,000 and was primarily attributable to a
decline in inventory and accounts receivable offset by a decrease in accounts
payable.

During the first quarter of fiscal 2002, capital expenditures totaled $5.8
million. Of the $5.8 million, approximately $4.7 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 and discrete semiconductor assembly and
test areas. We are creating a GaAs IC line that will allow the manufacture of
product on six-inch wafers. We are in the initial stages of development of this
six-inch wafer production line, which we estimate will cost approximately $30
million. We expect to complete this project within eighteen months. 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 $1.1 million of capital expenditures.

We believe that anticipated cash from operations, available funds and borrowings
under our revolving credit agreement, together with 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.
