`
`
`I, Jinsung Choi, declare as follows:
`
`lis
`
`I am currently employed by Qorvo,Inc., which is an American semiconductor
`
`company that designs, manufactures, and supplies radio-frequency (RF) systems and solutions
`
`for wireless and broadband communications.
`
`I have worked at Qorvo for approximately six
`
`years. At Qorvo, I am a memberofthe technical staff. In that role, I contribute to the design of
`
`RF components such as switches and low noise amplifiers. A copy of my curriculum vitae is
`
`attached hereto as Exhibit A.
`
`2.
`
`I earned my Bachelorof Science degreein electrical engineering from Pohang
`
`University of Science and Technology in South Korea in 2003. I earned my Doctor of
`
`Philosophy degree in electrical engineering from Pohang University of Science and Technology
`
`in 2009.
`
`3.
`
`I am the co-authorof a paperentitled “Envelope Tracking Power Amplifier
`
`Robust to Battery Depletion” (the “Choi 2010 paper’’), submitted as Exhibit B to this declaration.
`
`The paper waspublished bythe Institute of Electrical and Electronics Engineers (IEEE) in 2010.
`
`According to the IEEE website (https://ieeexplore.ieee.org/document/5517825/), the paper was
`
`added to IEEE’s digital library—IEEE Xp/lore—on July 23, 2010.
`

`
`Earlier in 2010, I attended the IEEE International Microwave Symposium
`
`(“IMS”) 2010 conference, held in Anaheim, California from May 23 to 28, 2010. The IMSis an
`
`annual technical conference for professionals specializing in RF/microwave theory and
`
`applications. The conference is well publicized in the field, and is open to any memberof the
`
`public interested in the topic. On information and belief, the IMSis the largest gathering of
`
`RF/microwaveprofessionals in the world.
`
`=
`
`The IMS 2010 conference was attended by hundreds of people. These attendees
`
`included many engineers specializing in RF circuit and power supply design for RF. The
`
`- 1 -
`
`
`
`conference included, for example, leading engineers in these areas from academia and industry,
`
`including many electrical engineers with multiple years’ experience designing RF circuits and/or
`
`powersupplies. At the time of the IMS 2010 conference, I had earned my doctorate in electrical
`
`engineering and had overfive years’ experience designing RF circuits and power supplies.
`
`6.
`
`I presented the Choi 2010 paperat the IMS 2010 conference during the Power
`
`Amplifier Circuits technical session on Wednesday, May 26, 2010. About a hundred people
`
`attended the session where I presented my paper, and there were also other parallel sessions.
`
`Te
`
`Before the IMS 2010 conference, a program book was madeavailable to
`
`attendees and potential attendees. A copy of that program bookis attached as Exhibit C. My
`
`presentationis listed on page 40 of the program book, in the middle column,near the bottom,at
`
`the WEPF-5 session. The programbook confirms my memorythat I presented the Choi 2010
`
`paper on Wednesday, May 26, 2010.
`
`8.
`
`People registering for IMS 2010 could pay a small extra fee to receive a USB
`
`drive. The fees for registration and the USB drive are shownat page 9 of the program book
`
`(Exhibit C). My understanding is that each USB drive contained PDF copies of the presented
`
`papers, including a copy of my Choi 2010 paper.
`
`9.
`
`I also recall that IMS 2010 had printing stations set up at the conference venue.
`
`Attendees could use any of these printing stations to print a copy of any paper being presented at
`
`the conference, including my own paper. These printing stations are mentioned on page 5 of the
`
`program book (Exhibit C), which states that “Print on Demand (PoD)is back again and will be
`
`available at a centralized station located in the Registration area at the Anaheim Convention
`
`Center. This will allow all registered attendees to print out any paper FREE!” This is whatI
`
`recall seeing at IMS 2010.
`
`
`
`10.
`
`No confidentiality restrictions were imposed on attendees at IMS 2010, and no
`
`confidentiality restrictions were placed on any of the papers contained on the USBdrives.
`
`Attendees were free to disseminate and discuss the technical material presented during the
`
`conference.
`
`11.
`
`Iam not receiving any compensation for my declaration or testimonyin this
`
`matter, aside from my standard Qorvo salary, which does not depend on my submission ofthis
`
`declaration orits contents.
`
`12.
`
`I declare that all statements made herein of my own knowledge are true and that
`
`all statements made on information and belief are believed to be true; and furtherthat these
`
`statements were made with the knowledgethat willful false statements and the like are
`
`punishable by fine or imprisonment, or both, under Section 1101 of Title 18 of the United States
`
`Code.
