講演「A Case Study of IT Convergence: Multi Mode/Band Transceiver」
Prof. Kukjin Chun （Seoul National University）
講演内容（Abstract）
For convergence era, there is need for a device to support a wide
range of frequencies. In addition, the demand for complex devices has
been increased as various standards such as m-WiMAX, LTE,
etc. emerge. In addition, the structure of a multi-mode /multi-band RF
transceiver is shifted from a multi-chain architecture to a
reconfigurable architecture. This shift is caused by the growth of
wireless communications to include a common vision of the fourth
generation of mobile communications, ubiquitous information access,
higher data rates and higher mobility. To deal with this change,
development of multi-mode / multi-band transceiver module based on
reconfigurable RF technology will be a stepping-stone for future high
speed wireless data communications.
In his talk, he will address a wireless transceiver which will be
useful for 4th generation mobile communication covering mobile WiMAX
and WLAN up to 5 GHz regime to match with IEEE 802.11n and 802.16e
standard. The developed transceiver is 7cm x 3.5cm in its size and it
has 2x2 MIMO and OFDM capacity with a single reconfigurable RFIC
ranging 2-6GHz as well as quad-band switchable Front-end module (FEM)
for band/mode selection. The reconfigurable RFIC has RF pins
consisting of 2Rx I/O and 2Tx I/O and is fabricated as 9mm x 9mm MLF
package at low cost. The size of the RFIC die was 5.7mm x 5.7mm and 81
inductors were used. The FEM is made of MEMS technology which is his
research interest to reduce the size and power dissipation. The
measured insertion loss of the developed FEM for Europe, America, and
Korea was 5.9dB, 5.8dB, and 5.9dB, respectively. Using embedded PCB
technology, the transceiver system was integrated and the area is 9%
smaller than the area of non-embedded PCB.
講演者略歴(Biography)
Kukjin Chun is professor in the department of Electrical and Computer Engineering at Seoul National University (SNU), where he served as head of the department. He also was the director of the Inter-university Semiconductor Research Center of SNU, where he established government funded open infrastructure for MEMS fabrication which have been utilized by Samsung, LG and Hyundai. After receiving MS and PhD degree from the University of Michigan as well as BS degree from SNU, he joined Washington State University in 1986 and SNU in 1989. He is the President of the Institute of Electronics Engineers of Korea and the member of the National Academy of Engineering of Korea. He served as an editorial board member of Journal of Micromechanics and Microengineering and the Fellow of the Institute of Physics of UK. He is serving on the Advisory Committee of the Institute of Electrical Engineering of Japan and on the International Advisory Committee of the LIMMS of University of Tokyo.
