         RE:       Registration Statement on Form S-3
                   Relating to 46,211 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 46,211 shares of the Company's common stock, $0.25 par value
per share (the "Shares").

         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.

         Based upon and subject to the foregoing, we are of the opinion that the
Shares have been validly 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
