     We are a radio frequency silicon and systems company, providing
high-performance radio frequency tuners, upstream amplifiers and transceivers to
the broadband communications markets. Using proprietary technologies and
advanced design methodologies, we have designed and developed radio frequency
integrated circuits and radio frequency systems, called modules, for a variety
of broadband communications access devices, including cable modems, PC/TVs
(which are multimedia personal computers with broadband reception capabilities),
set-top boxes, digital TVs and other consumer electronic devices. Our radio
frequency products are the gateway devices for reception of video, audio, data
and/or voice over existing broadband communications infrastructures, such as
cable and terrestrial. Our tuners receive and tune radio frequency signals,
transferring a selected signal (or channel) to the rest of the system's
electronics for further operation. Our upstream amplifiers transmit radio
frequency data from the user through the broadband system, amplifying the signal
to levels required by the network. Our transceivers, consisting of both tuners
and upstream amplifiers, enable interactivity by permitting two-way, or
bi-directional, communications. Our latest radio frequency integrated circuit
products offer a high level of integration, resulting in significant cost,
performance, size, reliability and manufacturability benefits. Our radio
frequency module products provide a complete, manufacturing-ready radio
frequency system, eliminating a customer's need for radio frequency design and
manufacturing expertise.

     We are a Delaware corporation with our principal executive offices located
at 2201 Tenth Street, Plano, Texas 75074. Our telephone number is (972)
673-1600. Our fiscal year ends on December 31. We maintain a website at
www.microtune.com. The reference to our website does not constitute
incorporation by reference of the information contained at this site. Microtune,

                              SELLING STOCKHOLDERS

     On November 28, 2001, we acquired Transilica Inc. pursuant to the terms of
an Agreement and Plan of Merger and Reorganization. In this merger, the selling
stockholders received shares of our common stock and cash in exchange for their
outstanding shares of Transilica common and preferred stock. In connection with
this merger, we agreed to register the resale by the selling stockholders of the
shares issued to the selling stockholders in this merger.

     The following table sets forth the number of shares beneficially owned by
each of the selling stockholders. None of the selling stockholders has had a
material relationship with us within the past three years other than as a result
of the ownership of our common stock or other securities of ours or as a result
of their employment with us as of the date of the closing of the acquisition of
Transilica. No estimate can be given as to the amount of our common stock that
will be beneficially owned by the selling stockholders after completion of this
offering because the selling stockholders may offer all, some or none of the
shares of our common stock beneficially owned by them. The shares offered by
this prospectus may be offered from time to time by the selling stockholders
named below.

     Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission. Except as set forth below, the persons named
in this table have sole voting and investment power with respect to all shares
of common stock shown as beneficially owned by them. The number of outstanding
shares of our common stock as of December 13, 2001 was 52,728,166 (including
5,000,000 shares of our common stock to be sold in our public offering which is
expected to close on December 19, 2001).

(1)  Shares are subject to a right of repurchase in favor of the Company that
     lapses with the passing of time pursuant to either (a) an Employee
     Restricted Stock Agreement dated May 6, 2000 or (b) an early exercise of a
     stock option grant pursuant to the terms and conditions of the Transilica
     Inc. 2000 Stock Option, Deferred Stock and Restricted Stock Plan.

(2)  Shares are subject to a Lock-Up Agreement by and between the stockholder
     and the Company dated approximately November 18, 2001 pursuant to which the
     transfer of the shares is restricted until December 28, 2002, except that
     this restriction shall expire with respect to ten percent (10%) of the
     shares on (a) the date that is the earlier of (i) February 28, 2001 or (ii)
     recognition by Transilica Inc. of $3 million of cumulative product revenue
     recognized in accordance with generally accepted accounting principles
     (such earlier date referred to as the "Lock-Up Termination Date"); and (b)
     each monthly anniversary of the Lock-Up Termination Date.

(3)  Because each selling stockholder may sell all or some of the shares
     registered on its behalf, from time to time as more fully described on the
     following page, subject to the restrictions in (1) and (2) above, if
     applicable, no estimate can be given at this time as to how many shares of
     Common Stock will be owned by each selling stockholder after the offering.

(4)  Because each selling stockholder may sell all or some of the shares
     registered on its behalf subject to the restrictions in (1) and (2), if
     applicable, no estimate can be given at this time as to the percentage of
     shares owned by each selling stockholder after the completion of the
     offering.

(5)  Hock Law was the former President and Chief Executive Officer of Transilica
     Inc. which was acquired by Microtune, Inc. on November 28, 2001. Hock Law
     currently serves as Executive Vice President and General Manager, Wireless
     Connectivity Division, of Microtune, Inc.

     shares of our common stock with the exception of Smart Technology Ventures
     III SBIC, L.P., which owns 2.66%; SOFTBANK Technology Ventures VI, L.P.,
     which owns 1.27%; and SOFTBANK U.S. Ventures Fund VI L.P., which owns 1.36%

     stockholders.

                              PLAN OF DISTRIBUTION

     We are registering 7,206,125 shares of our common stock on behalf of the
selling stockholders. As used herein, "selling stockholders" includes the
selling stockholders (including the former President and Chief Executive Officer
of Transilica who is, as of the date of this prospectus, our Executive Vice
President and General Manager, Wireless Connectivity Division) named in the
table above and pledgees, donees, transferees or other successors-in-interest
selling shares received from a named selling stockholder as a gift, partnership
distribution or other non-sale-related transfer after the date of this
prospectus. The selling stockholders may sell the shares from time to time and
may also decide not to sell all the shares they are allowed to sell under this
prospectus. The selling stockholders will act independently of us in making
decisions with respect to the timing, manner and size of each sale. The sales
may be made on one or more exchanges or in the over-the-counter market or
otherwise, at prices and at terms then prevailing or at prices related to the
then current market prices, or in negotiated transactions. The selling
stockholders may effect such transactions by selling the shares to or through
broker-dealers. The shares may be sold by one or more of, or a combination of,
the following:

     .    a block trade in which the broker-dealer so engaged will attempt to
          sell shares as agent but may position and resell a portion of the
          block as principal to facilitate the transaction;

     .    purchases by a broker-dealer as principal and resale by such
          broker-dealer for its account pursuant to this prospectus;

     .    an exchange distribution in accordance with the rules of such
          exchange;

     .    ordinary brokerage transactions and transactions in which the broker
          solicits purchasers; and

     .    privately negotiated transactions.

     To the extent required, this prospectus may be amended or supplemented from
time to time to describe a specific plan of distribution. In effecting sales,
broker-dealers engaged by the selling stockholders may arrange for other
broker-dealers to participate in the resales.

     The selling stockholders may enter into hedging transactions with
broker-dealers in connection with distributions of shares or otherwise. In such
transactions, broker-dealers may engage in short sales of shares in the course
of hedging the positions they assume with selling stockholders. The selling
stockholders also may sell shares short and redeliver shares to close out such
short positions. The selling stockholders may enter into option or other
transactions with broker-dealers which require the delivery of shares to the
broker-dealer. The broker-dealer may then resell or otherwise transfer such
shares pursuant to this prospectus. The selling stockholders also may loan or
pledge shares to a broker-dealer. The broker-dealer may sell the shares so
loaned, or upon a default the broker-dealer may sell the shares so pledged,
pursuant to this prospectus.

     Broker-dealers or agents may receive compensation in the form of
commissions, discounts or concessions from selling stockholders. Broker-dealers
or agents may also receive compensation from the purchasers of shares for whom
they act as agents or to whom they sell as principals, or both. Compensation as
to a particular broker-dealer might be in excess of customary commissions and
will be in amounts to be negotiated in connection with transactions involving
shares. Broker-dealers or agents and any other participating broker-dealers or
the selling stockholders may be deemed to be "underwriters" within the meaning
of Section 2(11) of the Securities Act of 1933 in connection with sales of
shares. Accordingly, any such commission, discount or concession received by
them and any profit on the resale of shares purchased by them may be deemed to
be underwriting discounts or commissions under the Securities Act of 1933.
Because selling stockholders may be deemed to be "underwriters" within the
meaning of Section 2(11) of the Securities Act of 1933, the selling stockholders
will be subject to the prospectus delivery requirements of the Securities Act of
1933. In addition, any shares of a selling stockholder covered by this
prospectus which qualify for sale pursuant to Rule 144 promulgated under the
Securities Act of 1933 may be sold under Rule 144 rather than pursuant to this
prospectus. The selling stockholders have advised us that they have not entered
into any agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their shares.

     The shares may be sold by selling stockholders only through registered or
licensed brokers or dealers if required under applicable state securities laws.
In addition, in certain states the shares may not be sold unless they have been
registered or qualified for sale in the applicable state or an exemption from
the registration or qualification requirement is available and such sale
complies with such exemption.

                                       6



     Under applicable rules and regulations under the Securities Exchange Act of
1934, any person engaged in the distribution of shares may not simultaneously
engage in market making activities with respect to our common stock for a period

addition, each selling stockholder will be subject to applicable provisions of
the Securities Exchange Act of 1934 and the associated rules and regulations
under the Securities Exchange Act of 1934, including Regulation M, which

any sale of the shares.

     We will file a supplement to this prospectus, if required, pursuant to Rule
424(b) under the Securities Act of 1933 upon being notified by a selling
stockholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares through a block trade, special offering,
exchange distribution or secondary distribution or a purchase by a broker or
dealer. Such supplement will disclose:

     .    the name of each such selling stockholder and of the participating
          broker-dealer(s);

     .    the number of shares involved;

     .    the price at which such shares were sold;

     .    the commissions paid or discounts or concessions allowed to such
          broker-dealer(s), where applicable;

     .    that such broker-dealer(s) did not conduct any investigation to verify
          the information set out or incorporated by reference in this
          prospectus; and

     .    other facts material to the transaction.

     We will bear all costs, expenses and fees in connection with the
registration of the shares. The selling stockholders will bear all commissions
and discounts, if any, attributable to the sales of the shares. The selling
stockholders may agree to indemnify any broker-dealer or agent that participates
in transactions involving sales of the shares against certain liabilities,
including liabilities arising under the Securities Act of 1933.

Item 15.  Indemnification Of Officers And Directors.

   Delaware law provides that a corporation has the ability to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding if the person acted
in good faith and in a manner the person reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe the person's
conduct was unlawful. Our amended and restated certificate of incorporation
provides that our directors will not be personally liable to us or our
stockholders for monetary damages for breach of fiduciary duty as a director to
the maximum extent permitted by Delaware law. Our Bylaws provide that the
Registrant shall indemnify its directors, officers, employees and agents to the
fullest extent permitted by Delaware law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. In addition, we
have entered into separate indemnification agreements with our directors,
officers and certain employees that require us to indemnify those individuals
against certain liabilities which may arise by reason of their status or service
(other than liabilities arising from willful misconduct of a culpable nature).
We also maintain director and officer liability insurance for these individuals.

   These indemnification provisions and the indemnification agreement to be
entered into between the Registrant and its officers and directors may be
sufficiently broad to permit indemnification of the Registrant's officers and
directors for liabilities (including reimbursement of expenses incurred) arising
under the Securities Act of 1933.

   The above discussion of our Amended and Restated Certificate of
Incorporation, our Bylaws and Section 145 of the Delaware General Corporation
Law and any indemnification agreements is not intended to be exhaustive and is
qualified in its entirety by such documents and statute.

Item 17. Undertakings

     Insofar as indemnification by the Registrant for liabilities arising under
the Securities Act of 1933 may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the provisions referenced in
Item 15 of this Registration Statement or otherwise, the Registrant has been
advised that in the opinion of the Securities and Exchange Commission
indemnification is against public policy as expressed in the Securities Act of
1933, and is, therefore, unenforceable. In the event that a claim for
indemnification against liabilities (other than the payment by the Registrant of
expenses incurred or paid by a director, officer, or controlling person of the
Registrant in the successful defense of any action, suit or proceeding) is
asserted by a director, officer or controlling person in connection with the
securities being registered hereunder, the Registrant will, unless in the
opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether
indemnification by it is against public policy as expressed in the Securities
Act of 1933 and will be governed by the final adjudication of that issue.

The undersigned Registrant hereby undertakes:

    1. To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

       (i)   To include any prospectus required by section 10(a)(3) of the
    Securities Act of 1933.

       (ii)  To reflect in the prospectus any facts or events arising after the
    effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in the
    Registration Statement. Notwithstanding the foregoing, any increase or
    decrease in volume of securities offered (if the total dollar value of
    securities offered would not exceed that which was registered) and any
    deviation from the low or high end of the estimated maximum offering range
    may be reflected in the form of prospectus filed with the Securities and
    Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective Registration Statement.

       (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or any
    material change to such information in the registration statement.

       Provided, however, that paragraphs (i) and (ii) do not apply if the
    information required to be included in a post-effective amendment by those
    paragraphs is contained in periodic reports filed by the Registrant pursuant
    to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that
    are incorporated by reference in this Registration Statement.

    2. That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

                                      II-2



    3. To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

    4. For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of Prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act of 1933 shall be deemed to be part of this Registration
Statement as of the time it was declared effective; and

    5. For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of Prospectus shall be
deemed to be a new Registration Statement relating to the securities offered
therein, and the offering of the securities at the time shall be deemed to be
the initial bona fide offering thereof.

    The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                                      II-3



                                   SIGNATURES

Registrant certifies that it has reasonable grounds to believe that it meets all
