Ladies and Gentlemen:

         I refer to the registration statement on Form S-3 (the "Registration
Statement") under the Securities Act of 1933, as amended, filed by Skyworks
Solutions, Inc., a Delaware corporation (the "Company"), with the Securities and
Exchange Commission (the "Commission") on or about July 15, 2002. The
Registration Statement covers 18,910,606 shares of Common Stock of the Company,
$0.25 par value per share (the "Shares"), which may be issued from time to time
in connection with the Washington Sub, Inc. 2002 Stock Option Plan (the "Plan").

         I have made such legal and factual examinations and inquiries as I
deemed advisable for the purpose of rendering this opinion. I am familiar with
the proceedings taken and proposed to be taken in connection with the
authorization, issuance and sale of the Shares. Based on my examination and
inquiries, it is my opinion that the Shares, upon issuance thereof in accordance
with the terms of the Plan and the Registration Statement, will be validly
issued, fully paid and non-assessable.

         This opinion is expressly limited to the matters set forth above and I
render no opinion, whether by implication or otherwise, as to any matters
relating to the Company or the Plan. I hereby consent to the filing of this
opinion as an exhibit to the Registration Statement.

                                              Very truly yours,

                                              /s/ Daniel N. Yannuzzi
                                              ----------------------------------
