                  Notes Due November 2007, and 25,412,960 shares of Common Stock

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 $230,000,000 aggregate principal amount of 4.75% Convertible
Subordinated Notes due November 2007 of the Company (the "Notes"), and up to
25,412,960 shares of the Company's common stock, $0.25 par value per share (the
"Shares"), which may be issued upon the conversion of the 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 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 12, 2002 (the
"Indenture"), between the Company and State Street Bank & Trust Company, 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 Notes have been duly authorized and issued, and are binding obligations
of the Company entitled to the benefits of the Indenture, and (ii) the Shares,
when issued upon conversion of the Notes in accordance with the terms of the
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
