                           [REVERSE SIDE OF SECURITY]

                            SKYWORKS SOLUTIONS, INC.

                    15% CONVERTIBLE SENIOR SUBORDINATED NOTE
                                DUE JUNE 30, 2005

1.       Interest

              Skyworks Solutions, Inc., a Delaware corporation (the "Company",
which term shall include any successor corporation under the Indenture
hereinafter referred to), promises to pay interest on the principal amount of
this Security at the rate of 15% per annum. The Company shall pay interest
quarterly on the last Business Day of each March, June, September and December,
commencing December 31, 2002; provided, however, that such interest may be
increased by any Additional Interest accruing from time to time on the principal
amount of this Security as provided in the Registration Rights Agreement. Any
reference herein to interest accrued or payable as of any date shall include any
Additional Interest accrued or payable on such date as provided in the
Registration Rights Agreement. Interest on the Securities shall accrue from the
most recent date to which interest has been paid on the Securities or the
Interim Convertible Note (as defined in the Refinancing Agreement) or, if no
interest has been paid, from November 12, 2002; provided, however, that if there
is not an existing Default in the payment of interest and if this Security is
authenticated between a record date referred to on the face hereof and the next
succeeding interest payment date, interest shall accrue from such interest
payment date. Interest will be computed on the basis of a 360-day year of twelve
30-day months.

              Notwithstanding the foregoing provisions of this paragraph 1, but
subject to applicable law, any overdue interest on this Security or any
principal of this Security due pursuant to paragraph 16 of this Security shall
bear interest, payable on demand in immediately available funds, for each day
from the date payment thereof was due to the date of actual payment, at a rate
equal to the sum of (1) the interest rate then otherwise applicable and (2) an
additional 1% per annum, or, if an Event of Default described in clause (i),
(iii), (vii) or (viii) of paragraph 16 has occurred and is continuing, this
Security shall bear interest, from the date of the occurrence of such Event of
Default until such Event of Default is cured or waived, payable on demand in
immediately available funds, at a rate equal to the sum of (1) the interest rate
then otherwise applicable and (2) an additional 1% per annum. Subject to
applicable law, any interest that shall accrue on overdue interest on this
Security as provided in the preceding sentence, and that shall not have been
paid in full on or before the next interest payment date to occur after the date

                                       7
<PAGE>
on which the overdue interest became due and payable, shall itself be deemed to
be overdue interest on this Security to which the preceding sentence shall
apply.

              In the event that any interest rate(s) provided for in this
paragraph 1 shall be determined to be unlawful, such interest rate(s) shall be
computed at the highest rate permitted by applicable law. Any payment by the
Company of any interest amount in excess of that permitted by law shall be
considered a mistake, with the excess being applied to the principal amount of
this Security without prepayment premium or penalty; if no such principal amount
is outstanding, such excess shall be returned to the Company.

2.       Method of Payment

              On the Maturity Date, the Company shall pay the principal amount
of this Security by issuing and delivering a number of whole shares of Common
Stock equal to the principal amount of the Security due and payable on the
Maturity Date divided by the Applicable Conversion Price in effect on the
Maturity Date, together with cash in lieu of any fractional shares pursuant to
Section 5.03 of the Indenture. The Company shall pay interest on this Security
(except defaulted interest) to the person who is the Holder of this Security at
the close of business on the March 15, June 15, September 15 or December 15, as
the case may be, next preceding the related interest payment date. The Holder
must surrender this Security to a Paying Agent to collect payment of principal.
Principal payable pursuant to paragraph 16 is payable in cash upon acceleration
for an Event of Default described in clause (i), (iii), (vii) or (viii) of the
first sentence of paragraph 16 and is payable in shares of Common Stock upon
acceleration for any other Event of Default. The Company will pay the Optional
Redemption Price, the Change in Control Purchase Price, principal payable in
cash pursuant to paragraph 16, cash in lieu of any fractional shares pursuant to
Section 5.03 of the Indenture and interest in money of the United States that at
the time of payment is legal tender for payment of public and private debts. The
Company may, however, pay such Optional Redemption Price, Change in Control
Purchase Price, principal, cash in lieu of any fractional shares and interest in
respect of any Certificated Security by check or wire payable in such money;
provided, however, that a Holder with an aggregate principal amount in excess of
$2,000,000 will be paid by wire transfer in immediately available funds at the
election of such Holder. The Company may mail an interest check to the Holder's
registered address. Notwithstanding the foregoing, so long as this Security is
registered in the name of a Depositary or its nominee, all payments hereon shall
be made by wire transfer of immediately available funds to the account of the
Depositary or its nominee.

3.       Paying Agent, Registrar and Conversion Agent

              Initially, Wachovia Bank, National Association (the "Trustee,"
which term shall include any successor trustee under the Indenture hereinafter
referred to) will act as

                                       8
<PAGE>
Paying Agent, Registrar and Conversion Agent. The Company may change any Paying
Agent, Registrar or Conversion Agent without notice to the Holder. The Company
or any of its Subsidiaries may, subject to certain limitations set forth in the
Indenture, act as Paying Agent or Registrar.

4.       Indenture, Limitations

              This Security is one of a duly authorized issue of Securities of
the Company designated as its 15% Convertible Senior Subordinated Notes Due June
30, 2005 (the "Securities") issued under an Indenture dated as of November 20,
2002 (together with any supplemental indentures thereto, the "Indenture")
between the Company and the Trustee. Capitalized terms herein are used as
defined in the Indenture unless otherwise defined herein. The terms of this
Security include those stated in the Indenture and those required by or made
part of the Indenture by reference to the Trust Indenture Act of 1939, as
amended, as in effect on the date of the Indenture. This Security is subject to
all such terms, and the Holder of this Security is referred to the Indenture and
said Act for a statement of them. The Securities are senior subordinated
unsecured obligations of the Company limited to $45 million aggregate principal
amount, subject to Section 2.10 of the Indenture, and are "Designated Senior
Indebtedness" (as defined in the Junior Notes Indenture) for purposes of the
Junior Notes Indenture. The Indenture does not limit other debt of the Company,
secured or unsecured, including Senior Indebtedness.

5.       Optional Redemption

              The Company shall not have the option to redeem the Securities
pursuant to this paragraph 5 prior to May 12, 2004. Thereafter, the Company
shall have the option to redeem any portion of the Securities (an "Optional
Redemption") upon giving notice as set forth in paragraph 6. The Optional
Redemption Price (expressed as a percentage of the principal amount) shall be
103%, together with accrued interest up to but not including the date of
redemption (the "Optional Redemption Date"), payable in cash, provided that if
the Optional Redemption Date falls after an interest payment record date and on
or before an interest payment date, then the interest payment will be payable to
the Holders in whose names the Securities are registered at the close of
business on the relevant record date for payment of such interest.

6.       Notice of Redemption

              Notice of redemption will be mailed or delivered at least 20 days
but not more than 60 days before the Optional Redemption Date to each Holder of
Securities to be redeemed at its registered address. Securities in denominations
larger than $1,000 may be redeemed in part, but only in whole multiples of
$1,000. On and after the Optional Redemption Date, subject to the deposit with
the Paying Agent of funds sufficient to pay

                                       9
<PAGE>
in cash the Optional Redemption Price plus accrued interest, if any, to, but
excluding, the Optional Redemption Date, interest shall cease to accrue on
Securities or portions of them called for redemption.

7.       Purchase of Securities at Option of Holder Upon a Change in Control

              At the option of the Holder and subject to the terms and
conditions of the Indenture, the Company shall be obligated to purchase all or
any part specified by the Holder (so long as the principal amount of such part
is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities
held by such Holder on the date that is no less than 30 days and not more than
60 days after notice of the occurrence of a Change in Control is given as
provided in Section 4.07, at a purchase price in cash equal to 100% of the
principal amount thereof together with accrued interest up to, but excluding,
the Change in Control Purchase Date. The Holder shall have the right to withdraw
any Change in Control Purchase Notice (in whole or in a portion thereof that is
$1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to
the close of business on the Business Day next preceding the Change in Control
Purchase Date by delivering a written notice of withdrawal to the Paying Agent
in accordance with the terms of the Indenture.

8.       Conversion

              A Holder of a Security may convert the principal amount of such
Security (or any portion thereof equal to $1,000 or any integral multiple of
$1,000 in excess thereof) into shares of Common Stock at any time after 60 days
from November 12, 2002 and prior to the close of business on the Business Day
immediately preceding June 30, 2005; provided, however, that if the Security is
called for redemption or subject to purchase upon a Change in Control, the
conversion right will terminate at the close of business on the Business Day
immediately preceding the Optional Redemption Date or the Change in Control
Purchase Date, as the case may be, for such Security or such earlier date as the
Holder presents such Security for redemption or purchase (unless the Company
shall default in making the Optional Redemption Price payment or Change in
Control Purchase Price payment, as the case may be, when due, in which case the
conversion right shall terminate at the close of business on the date such
default is cured and such Security is redeemed or purchased). The initial
Conversion Price is $7.87 per share, subject to adjustment under certain
circumstances. The number of shares of Common Stock issuable upon conversion of
a Security is determined by dividing the principal amount of the Security or
portion thereof converted by the Applicable Conversion Price as of the related
Conversion Date. No fractional shares will be issued upon conversion; in lieu
thereof, an amount will be paid in cash based upon the Closing Price (as defined
in the Indenture) of the Common Stock on the Trading Day immediately prior to
the Conversion Date. To convert a Security, a Holder must (a) complete and

                                       10
<PAGE>
manually sign the conversion notice set forth below and deliver such notice to a
Conversion Agent, (b) surrender the Security to a Conversion Agent, (c) furnish
appropriate endorsements and transfer documents if required by a Registrar or a
Conversion Agent, and (d) pay any transfer or similar tax, if required.
Securities so surrendered for conversion (in whole or in part) during the period
from the close of business on any regular record date to the opening of business
on the next succeeding interest payment date (excluding Securities or portions
thereof which are either (i) called for redemption or (ii) subject to purchase
following a Change in Control, in either case, on a date during the period
beginning at the close of business on a regular record date and ending at the
opening of business on the first Business Day after the next succeeding interest
payment date, or if such interest payment date is not a Business Day, the second
such Business Day) shall also be accompanied by payment in funds acceptable to
the Company of an amount equal to the interest payable on such interest payment
date on the principal amount of such Security then being converted, and such
interest shall be payable to such registered Holder notwithstanding the
conversion of such Security, subject to the provisions of this Indenture
relating to the payment of defaulted interest by the Company. If the Company
defaults in the payment of interest payable on such interest payment date, the
Company shall promptly repay such funds to such Holder. A Holder may convert a
portion of a Security equal to $1,000 or any integral multiple thereof. A
Security in respect of which a Holder had delivered a Change in Control Purchase
Notice exercising the option of such Holder to require the Company to purchase
such Security may be converted only if the Change in Control Purchase Notice is
withdrawn in accordance with the terms of the Indenture.

9.       Conversion Arrangement on Call for Redemption

              Any Securities called for redemption, unless surrendered for
conversion before the close of business on the Business Day immediately
preceding the Optional Redemption Date, may be deemed to be purchased from the
Holders of such Securities at an amount not less than the Optional Redemption
Price, together with accrued interest, if any, to, but not including, the
Optional Redemption Date, by one or more investment bankers or other purchasers
who may agree with the Company to purchase such Securities from the Holders, to
convert them into Common Stock of the Company and to make payment for such
Securities to the Paying Agent in trust for such Holders.

10.      Subordination

              The indebtedness evidenced by the Securities is, to the extent and
in the manner provided in the Indenture, subordinate and junior in right of
payment to the prior payment in full of all Senior Indebtedness of the Company.
Any Holder by accepting this Security agrees to and shall be bound by such
subordination provisions and authorizes the Trustee to give them effect. In
addition to all other rights of Senior Indebtedness

                                       11
<PAGE>
described in the Indenture, the Senior Indebtedness shall continue to be Senior
Indebtedness and entitled to the benefits of the subordination provisions
irrespective of any amendment, modification or waiver of any terms of any
instrument relating to the Senior Indebtedness or any extension or renewal of
the Senior Indebtedness.

11.      Denominations, Transfer, Exchange

              The Securities are in registered form without coupons in
denominations of $1,000 and integral multiples of $1,000. A Holder may register
the transfer of or exchange Securities in accordance with the Indenture. The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes or other governmental
charges that may be imposed in relation thereto by law or permitted by the
Indenture.

12.      Persons Deemed Owners

              The Holder of a Security may be treated as the owner of it for all
purposes.

13.      Unclaimed Money and Shares of Common Stock

              If money or shares of Common Stock for the payment of principal or
interest remains unclaimed for two years, the Trustee or Paying Agent will pay
the money and deliver the shares of Common Stock back to the Company at its
written request. After that, Holders entitled to money or shares of Common Stock
must look to the Company for payment.

14.      Amendment, Supplement and Waiver

              Subject to certain exceptions, the Indenture or the Securities may
be amended or supplemented with the consent of the Holders of at least a
majority in principal amount of the Securities then outstanding, and an existing
Default or Event of Default and its consequence or compliance with any provision
of the Indenture or the Securities may be waived in a particular instance with
the consent of the Holders of a majority in principal amount of the Securities
then outstanding. Without the consent of or notice to any Holder, the Company
and the Trustee may amend or supplement the Indenture or the Securities to,
among other things, cure any ambiguity, defect or inconsistency or make any
other change that does not adversely affect the rights of any Holder.

15.      Successor Corporation

              When a successor corporation assumes all the obligations of its
predecessor under the Securities and the Indenture in accordance with the terms
and conditions of the

                                       12
<PAGE>
Indenture, the predecessor corporation will (except in certain circumstances
specified in the Indenture) be released from those obligations.

16.      Defaults and Remedies

              Under the Indenture, an Event of Default includes: (i) default for
15 days in payment of any interest on any Securities; (ii) default in payment of
any principal on the Securities when due at its Stated Maturity; (iii) failure

amount of the Securities then outstanding may direct the Trustee in its exercise
of any trust or power. The Trustee may withhold from Holders notice of any
continuing Default (except a Default in payment of principal or interest) if it
determines that withholding notice is in their interests. The Company is
required to file periodic reports with the Trustee as to the absence of Default.
