Dear Sir or Madam:

         We are counsel to Skyworks Solutions, Inc., a Delaware corporation (the
"Company"), and have represented the Company in connection with the preparation
and filing of the Company's Registration Statement on Form S-3 (the
"Registration Statement"), on or about the date hereof, covering the resale to
the public of up to $45,000,000 aggregate principal amount of 15% Convertible
Senior Subordinated Notes due June 30, 2005 of the Company (the "Senior Notes"),
and up to 7,147,395 shares of the Company's common stock, $0.25 par value per
share (the "Shares"), which may be issued upon the conversion or at maturity
(including upon certain acceleration events) of the Senior Notes.

         We have reviewed the corporate proceedings taken and proposed to be
taken by the Board of Directors of the Company with respect to the authorization
and issuance of the Senior Notes and the Shares. We have also examined and
relied upon originals or copies, certified or otherwise authenticated to our
satisfaction, of all corporate records, documents, agreements or other
instruments of the Company, including that certain Indenture, dated as of
November 20, 2002 (the "Indenture"), between the Company and Wachovia Bank,
National Association, and have made all investigations of law and have discussed
with the Company's officers all questions of fact that we have deemed necessary
or appropriate.

         Based upon and subject to the foregoing, we are of the opinion that (i)
the Senior Notes have been duly authorized and are binding obligations of the
Company entitled to the benefits of the Indenture, and (ii) the Shares, when
issued upon conversion or at maturity of the Senior Notes in accordance with the
terms of the Senior Notes, will be validly issued, fully paid and
non-assessable.

         We hereby consent to the filing of this opinion as Exhibit 5.01 to the
Registration Statement and to the reference to our firm in the Prospectus
contained in the Registration Statement under the caption "Legal Matters."


                               Very truly yours,

                               /s/ TESTA, HURWITZ & THIBEAULT, LLP
