(1) Pursuant to Rule 429 of the Securities Act of 1933, as amended (the
    "Securities Act"), the prospectus delivered to participants under the
    Registrant's 1994 Stock Option Plan, as amended (the "1994 Plan"), also
    relates to an aggregate of 1,503,295 shares previously registered under Form
    S-8 Registration Nos. 333-2886, 333-52037 and 333-89275. Includes 750,000
    shares to be registered under the 1994 Plan and 200,000 shares to be
    registered under the 2000 Nonstatutory Stock Option Plan (the "2000 Plan").
(2) The Proposed Maximum Offering Price Per Share was estimated in part pursuant
    to Rule 457(h) under the Securities Act, and, in part, pursuant to Rule
    457(c) under the Securities Act. With respect to (i) 292,414 shares which
    are subject to outstanding options to purchase Common Stock under the 1994
    Plan and (ii) 93,500 shares which are subject to outstanding options to
    purchase Common Stock under the 2000 Plan, the Proposed Maximum Offering
    Price Per Share was estimated pursuant to Rule 457(h) under which Rule the
    per share price of options to purchase stock under an employee stock option
    plan may be estimated by reference to the exercise price of such options.
    The weighted average exercise price of the 292,414 shares subject to
    outstanding options under the 1994 Plan to be registered is $40.10. The
    weighted average exercise price of the 93,500 shares subject to outstanding
    options under the 2000 Plan to be registered is $48.50. With respect to (i)
    457,586 shares of Common Stock available for future grant under the 1994
    Plan and (ii) 106,500 shares of Common Stock available for future grant
    under the 2000 Plan, the Proposed Maximum Offering Price Per Share was
    estimated pursuant to Rule 457(c) whereby the per share price was determined
    by reference to the average between the high and low price reported in the
    Nasdaq National Market on November 9, 2000, which average was $34.375. The
    number referenced above in the table entitled "Proposed Maximum Offering
    Price Per Share" represents a weighted average of the foregoing estimates
    calculated in accordance with Rules 457(h) and 457(c).

                                     PART II

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT


Item 3. Incorporation of Documents by Reference

        Celeritek, Inc. (the "Company") hereby incorporates by reference in this
registration statement the following documents and information heretofore filed
with the Securities and Exchange Commission:

        (a) The Company's Annual Report on Form 10-K for the fiscal year ended
March 31, 2000, pursuant to Section 13 of the Securities Exchange Act of 1934,
as amended (the "Exchange Act").

        (b) The Company's Quarterly Reports on Form 10-Q for the fiscal quarters
ended June 30, 2000 and September 30, 2000, filed pursuant to Section 13 of the
Exchange Act.

        (c) All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the registrant document
referred to in (a) above.

        (d) The description of the Company's Common Stock to be offered hereby
is contained in the Company's Registration Statement on Form 8-A filed with the
Securities and Exchange Commission on November 2, 1995 pursuant to Section 12(g)
of the Exchange Act, including any amendment or report filed for the purpose of
updating such description.

        All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4. Description of Securities

        Not applicable.

Item 5. Interests of Named Experts and Counsel

        Not applicable.

Item 6. Indemnification of Directors and Officers

        The Company's Articles of Incorporation limit the liability of directors
for monetary damages to the maximum extent permitted by California law. Such
limitation of liability has no effect on the availability of equitable remedies,
such as injunctive relief or rescission.

        The Company's Bylaws provide that the Company will indemnify its
directors and officers and may indemnify its employees and agents (other than
officers and directors) against certain liabilities to the fullest extent
permitted by California law. The Company is also empowered under its Bylaws to
enter into


                                      II-1
<PAGE>   3


indemnification agreements with its directors and officers and to purchase
insurance on behalf of any person whom it is required or permitted to indemnify.
The Company has entered into indemnification agreements with each of its current
directors and officers which provide for indemnification of, and advancement of
expenses to, such persons to the greatest extent permitted by California law,
including by reason of action or inaction occurring in the past and
circumstances in which indemnification and advancement of expenses are
discretionary under California law. Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors, officers or
persons controlling the Company pursuant to the foregoing provisions, the
Company has been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

Item 7. Exemption From Registration Claimed

        Not applicable.

Item 8. Exhibits

        4.1*    1994 Stock Option Plan and form of Stock Option Agreement.

        4.2     2000 Nonstatutory Stock Option Plan and form of Stock Option
                Agreement.

                legality of securities being registered.

        23.1    Consent of Ernst & Young, LLP, Independent Auditors.

        23.2    Consent of Counsel (contained in Exhibit 5.1).

Item 9. Undertakings

        (a)    Rule 415 Offering  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 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.

               (2) That, for the purpose of determining any liability under the
Securities Act, 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.

               (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.

        (b)    Filing incorporating subsequent Exchange Act documents by
               reference

        The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) 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.

        (c)    Request for acceleration of effective date or filing of
registration statement on Form S-8

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such 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 such
director, officer or controlling person in connection with the securities being
registered, 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 such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

(1) Pursuant to Rule 429 of the Securities Act of 1933, as amended (the
    "Securities Act"), the prospectus delivered to participants under the
    Registrant's 1994 Stock Option Plan, as amended (the "1994 Plan"), also
    relates to an aggregate of 1,503,295 shares previously registered under Form
    S-8 Registration Nos. 333-2886, 333-52037 and 333-89275. Includes 750,000
    shares to be registered under the 1994 Plan and 200,000 shares to be
    registered under the 2000 Nonstatutory Stock Option Plan (the "2000 Plan").
(2) The Proposed Maximum Offering Price Per Share was estimated in part pursuant
    to Rule 457(h) under the Securities Act, and, in part, pursuant to Rule
    457(c) under the Securities Act. With respect to (i) 292,414 shares which
    are subject to outstanding options to purchase Common Stock under the 1994
    Plan and (ii) 93,500 shares which are subject to outstanding options to
    purchase Common Stock under the 2000 Plan, the Proposed Maximum Offering
    Price Per Share was estimated pursuant to Rule 457(h) under which Rule the
    per share price of options to purchase stock under an employee stock option
    plan may be estimated by reference to the exercise price of such options.
    The weighted average exercise price of the 292,414 shares subject to
    outstanding options under the 1994 Plan to be registered is $40.10. The
    weighted average exercise price of the 93,500 shares subject to outstanding
    options under the 2000 Plan to be registered is $48.50. With respect to (i)
    457,586 shares of Common Stock available for future grant under the 1994
    Plan and (ii) 106,500 shares of Common Stock available for future grant
    under the 2000 Plan, the Proposed Maximum Offering Price Per Share was
    estimated pursuant to Rule 457(c) whereby the per share price was determined
    by reference to the average between the high and low price reported in the
    Nasdaq National Market on November 9, 2000, which average was $34.375. The
    number referenced above in the table entitled "Proposed Maximum Offering
    Price Per Share" represents a weighted average of the foregoing estimates
    calculated in accordance with Rules 457(h) and 457(c).

               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference

        Celeritek, Inc. (the "Company") hereby incorporates by reference in this
registration statement the following documents and information heretofore filed
with the Securities and Exchange Commission:

        (a) The Company's Annual Report on Form 10-K for the fiscal year ended
March 31, 2000, pursuant to Section 13 of the Securities Exchange Act of 1934,
as amended (the "Exchange Act").

        (b) The Company's Quarterly Reports on Form 10-Q for the fiscal quarters
ended June 30, 2000 and September 30, 2000, filed pursuant to Section 13 of the
Exchange Act.

        (c) All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the registrant document
referred to in (a) above.

        (d) The description of the Company's Common Stock to be offered hereby
is contained in the Company's Registration Statement on Form 8-A filed with the
Securities and Exchange Commission on November 2, 1995 pursuant to Section 12(g)
of the Exchange Act, including any amendment or report filed for the purpose of
updating such description.

        All documents subsequently filed by the Company pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a
post-effective amendment to this registration statement which indicates that all
securities offered hereby have been sold or which deregisters all securities
remaining unsold, shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 4. Description of Securities

        Not applicable.

Item 5. Interests of Named Experts and Counsel

        Not applicable.

Item 6. Indemnification of Directors and Officers

        The Company's Articles of Incorporation limit the liability of directors
for monetary damages to the maximum extent permitted by California law. Such
limitation of liability has no effect on the availability of equitable remedies,
such as injunctive relief or rescission.

        The Company's Bylaws provide that the Company will indemnify its
directors and officers and may indemnify its employees and agents (other than
officers and directors) against certain liabilities to the fullest extent
permitted by California law. The Company is also empowered under its Bylaws to
enter into

                                      II-1
3

indemnification agreements with its directors and officers and to purchase
insurance on behalf of any person whom it is required or permitted to indemnify.
The Company has entered into indemnification agreements with each of its current
directors and officers which provide for indemnification of, and advancement of
expenses to, such persons to the greatest extent permitted by California law,
including by reason of action or inaction occurring in the past and
circumstances in which indemnification and advancement of expenses are
discretionary under California law. Insofar as indemnification for liabilities
arising under the Securities Act may be permitted to directors, officers or
persons controlling the Company pursuant to the foregoing provisions, the
Company has been informed that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

Item 7. Exemption From Registration Claimed

        Not applicable.

Item 8. Exhibits

        4.1*    1994 Stock Option Plan and form of Stock Option Agreement.

        4.2     2000 Nonstatutory Stock Option Plan and form of Stock Option
                Agreement.

                legality of securities being registered.

Item 9. Undertakings

        (a)    Rule 415 Offering  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 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.

               (2) That, for the purpose of determining any liability under the
Securities Act, 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.

               (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.

        (b)    Filing incorporating subsequent Exchange Act documents by
               reference

        The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) 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.

        (c)    Request for acceleration of effective date or filing of
registration statement on Form S-8

        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such 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 such
director, officer or controlling person in connection with the securities being
registered, 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 such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
