Murata's method will become an IC standard next year. Murata ceramics are known as the best in the world. Dielectric constants range from 20 to 13,000. A value of 3000 is most popular. In addition, ferrite materials are used to develop transformers and noise suppression filters.
Pyroelectricity is a material property explored for sensor development.
Furthermore, semiconductor materials are used for the development of thermistors. The kind of device used for filtering depends inter alia on frequency and power levels. Thus SAW filters are good at lower power levels and better at the lower frequencies. Murata has a good capability to design microwave combline and stepped-impedance filters and duplexers to specified performance. Murata has written its own proprietary CAD programs to aid in various designs.
