POWER OF ATTORNEY

         I, Conrad Gagnon, hereby authorize and designate each of Clay Simpson,
Steve Coen and Jason Day, signing singly, as my true and lawful attorney-in-fact
to:

                  (1)   execute for and on my behalf, in my capacity as an officer
          and/or director of M/A-COM Technology Solutions Holdings, Inc. and its
          affiliates (the "Company"), the Form ID and Forms 3, 4 and 5 in
          accordance with Section 16(a) of the Securities Exchange Act of 1934,
          as amended (the "Exchange Act") and the rules and regulations
          promulgated thereunder;

                  (2)   do and perform any and all acts for and on my behalf which
          may be necessary or desirable to complete and execute any such Form ID
          or Form 3, 4 or 5 and timely file such form with the Securities and
          Exchange Commission, any stock exchange or similar authority; and

                  (3)   take any other action of any type whatsoever in connection
          with the foregoing which, in the opinion of such attorney-in-fact, may
          be to my benefit, in my best interest, or legally required of me, it
          being understood that the statements executed by such attorney-in-fact
          on my behalf pursuant to this Power of Attorney shall be in such form
          and shall contain such terms and conditions as such attorney-in-fact
          may approve in such attorney-in-fact's discretion.

         I hereby further grant to each such attorney-in-fact full power and
authority to do and perform any and every act and thing whatsoever requisite,
necessary, or proper to be done in the exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as I might or could do if
personally present, with full power of substitutes or revocation, hereby
ratifying and confirming all that such attorney-in-fact, or such
attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be
done by virtue of this Power of Attorney and the rights and powers herein
granted. I hereby acknowledge that the foregoing attorneys-in-fact, in serving
in such capacity at my request, are not assuming, nor is the Company assuming,
any of my responsibilities to comply with Section 16 of the Exchange Act.

         This Power of Attorney shall remain in full force and effect until I am
no longer required to file the Form ID or Forms 3, 4 and 5 with respect to my
holdings of and transactions in securities issued by the Company, unless earlier
revoked by me in a signed writing delivered to the foregoing attorneys-in-fact.

         IN WITNESS WHEREOF, I have caused this Power of Attorney to be duly
executed as of this 3rd day of March, 2012.

                                        /s/ Conrad Gagnon
