     RE:  Registration Statement on Form S-3
          Relating to 1,017,900 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 1,017,900 shares of the Company's common stock, $0.25 par
value per share (the "Shares"), which may be issued upon the exercise of an
outstanding warrant issued to Jazz Semiconductor, Inc. on June 25, 2002 (the
"Warrant").

     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 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 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.

     We are members only of the Bar of the Commonwealth of Massachusetts and are
not experts in, and express no opinion regarding, the laws of any jurisdiction
other than the Commonwealth of Massachusetts and the United States of America,
and the General Corporation Law of the State of Delaware.

     Based upon and subject to the foregoing, we are of the opinion that the
Shares when issued and paid for in accordance with the terms of the Warrant will
be legally issued, fully paid and non-assessable.

     We hereby consent to the filing of this opinion as Exhibit 5 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
