The application of microwave ceramics

Sumitomo Metal Industries, Ltd. (SMI) has developed and commercialized microwave dielectric ceramics with variable characteristics. We present and discuss the application of microwave ceramics at one of the ceramic components manufacturers. Microwave devices, such as co-axial dielectrics and the high frequency capacitor, are introduced. Further, a multi-layer dielectric resonator and a voltage control oscillator (VCO), which use the developed low firing materials, are also discussed.
