SAW in China (invited)

SAW research and development in China started in early nineteen seventies. Now, most kinds of SAW devices have been developed in China. However, the research, development and mass production fabrication in China is not matched to the huge market. In particular, the high frequency devices (GHz level), new generation filters (for example, high specification devices due to accurate simulation and optimization, new structures like multi-track devices, etc.), advanced fabrication technology and package technology with small size device design, etc. are to be developed. The main institutions in China are introduced. The state of the art of research, device development is described through some results of research and device developments in China. The situation of the SAW device industry in China is also introduced.
