Advances in GaN Device Technology for Millimeter-wave ApplicationsMillimeter-wave and sub-millimeter-wave applications, such as satellite communications, radar systems, high-speed wireless communications, and newly developed mobile 5G system, have demanded high power and high efficiency devices. GaN device is still a main player for the above frequencies and applications. This workshop will introduce the recent progress in GaN technology in millimeter-wave applications. This workshop will provide the bridge between a system/circuit designer and a device engineer. The workshop will start discussing the required performances for recent millimeter-wave applications including 5G system. After that, the workshop will cover the recent developed GaN devices for millimeter-wave and sub-millimeter-wave operation, device simulation, device modelling, and PA design techniques.1.Hiroshi Okazaki, NTT DOCOMO, “5G Applications (TBD)”2.Nicholas J.
