GREENSBORO, N.C., March 8, 2010 (GLOBE NEWSWIRE) -- RF Micro Devices,
Inc. (Nasdaq:RFMD), a global leader in the design and manufacture of
high-performance radio frequency components and compound semiconductor
technologies, today provided updated financial information for RFMD's
fiscal 2010 fourth quarter, ending April 3, 2010.

RFMD now expects to generate quarterly revenue of approximately $240
million to $245 million, which represents approximately 41%
year-over-year growth at the midpoint of this updated outlook. As a
result of the anticipated increase in revenue, RFMD expects to achieve
non-GAAP quarterly earnings per share of approximately $0.11 to $0.12.

RFMD is experiencing broad-based strength in its core business this
quarter, with current customer demand significantly outpacing original
expectations in both the cellular products group and multi-market
products group. RFMD is seeing particular strength in China and Korea
and expects continued market share gains across leading cellular
baseband providers and handset manufacturers this calendar year.

RFMD will present at 2:15 p.m. EST tomorrow, March 9, at the Raymond
James 31st Annual Institutional Investors Conference in Orlando,
Florida. A live audio webcast of the presentation will be available via
the RFMD(R) Investor Relations web page at: http://www.rfmd.com (under
Investors).

Non-GAAP Financial Measures

This press release contains a forward-looking estimate of net income
per diluted share that has not been calculated in accordance with
United States Generally Accepted Accounting Principles (GAAP).
Management uses certain non-GAAP financial measures, including net
income per diluted share, to develop an annual operating plan, to
assess whether research and development efforts are at an appropriate
level, and when making decisions about product spending, administrative
budgets and marketing programs. In addition, we believe that non-GAAP
financial measures provide useful supplemental information to investors
and enable investors to analyze the results of operations in the same
way as management. We have chosen to provide this supplemental
information to enable investors to perform additional comparisons of
operating results and to analyze financial performance excluding the
effect of certain non-cash expenses, share-based compensation expense
and other items, which may obscure trends in RFMD's underlying
performance. Non-GAAP financial measures should be considered as a
supplement to, and not as a substitute for, or superior to, the
corresponding measures calculated in accordance with GAAP, and may
differ from how other companies calculate or present similar non-GAAP
financial measures.

Non-GAAP net income per diluted share excludes the effects of the
following estimated expenses: share-based compensation expense,
amortization of intangible assets, non-cash interest expense on
convertible subordinated notes, adjustment for non-cash income taxes,
restructuring and integration charges, and manufacturing start-up
costs. As noted above, RFMD uses non-GAAP net income per diluted share
to assess its degree of achievement of existing corporate objectives
against its annual operating plan. We are unable to provide a
reconciliation of our forward-looking estimate of our fourth fiscal
quarter non-GAAP net income per diluted share to a forward-looking
estimate of our fourth fiscal quarter GAAP net income per diluted
share, however, because certain information needed to make a reasonable
forward-looking estimate is difficult to predict and estimate at this
time and is dependent on future events that are uncertain or outside of
our control. Our actual non-GAAP net income per diluted share for our
fourth quarter ending April 3, 2010 may differ from this
forward-looking non-GAAP net income per diluted share estimate, and
such differences may be material.

their traditional sources of credit to finance their operations, which
could lead them to reduce their level of support for us, variability in
operating results, the rate of growth and development of the markets we

systems business, including cellular transceivers, our ability to
execute on our plans to consolidate or relocate manufacturing
operations, our reliance on inclusion in third party reference designs
for a portion of our revenue, our ability to manage channel partner and
customer relationships, risks associated with the operation of our

in response to changes in demand for our products, dependence on a
limited number of customers for a substantial portion of our revenues,
dependence on gallium arsenide (GaAs) for the majority of our products,
