`

`

`I, Jinsung Choi, declare as follows:
`
`1.
`
`I am cuITently 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 member of the technical staff. In that role, I contribute to the design of
`
`RF components such as switches and low noise amplifiers. A copy of my cmTiculum vitae is
`
`attached hereto as Exhibit A.
`
`2.
`
`I earned my Bachelor of Science degree in 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-author of a paper entitled "Envelope Tracking Power Amplifier
`
`Robust to Battery Depletion" (the "Choi 2010 paper"), submitted as Exhibit B to this declaration.
`
`The paper was published by the Institute of Electrical and Electronics Engineers (IEEE) in 2010.
`
`According to the IEEE website (https://ieeexplore.ieee.org/document/5517825D, the paper was
`
`added to IEEE's digital library-IEEEXplore-on July 23, 2010.
`
`4.
`
`Earlier in 2010, I attended the IEEE International Microwave Symposium
`
`("IMS") 2010 conference, held in Anaheim, California from May 23 to 28, 2010. The IMS is 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 member of the
`
`public interested in the topic. On inf01mation and belief, the IMS is the largest gathering of
`
`RF/microwave professionals in the world.
`
`5.
`
`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
`
`power supplies. At the time of the IMS 2010 conference, I had earned my doctorate in electrical
`
`engineering and had over five years' experience designing RF circuits and power supplies.
`
`6.
`
`I presented the Choi 2010 paper at 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.
`
`7.
`
`Before the IMS 2010 conference, a program book was made available to
`
`attendees and potential attendees. A copy of that program book is attached as Exhibit C. My
`
`presentation is listed on page 40 of the program book, in the middle column, near the bottom, at
`
`the WEPF-5 session. The program.book confirms my memory that 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 shown at 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 what I
`
`recall seeing at IMS 2010.
`
`- 2 -
`
`

`

`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 USB drives.
`
`Attendees were free to disseminate and discuss the technical material presented during the
`
`conference.
`
`11.
`
`I am not receiving any compensation for my declaration or testimony in this
`
`matter, aside from my standard Qorvo salary, which does not depend on my submission of this
`
`declaration or its contents.
`
`12.
`
`I declare that all statements made herein of my own knowledge are true and that
`
`all statements made on inf01mation and belief are believed to be true; and further that these
`
`statements were made with the knowledge that 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.
