Microwave Dielectric Ceramics
Microwave dielectric ceramics improve the size of devices and the packaging density of microwave integrated circuits. For this reason, it is widely used for the microwave filters and circuit boards in the base station of mobile commucations and satellite communication systems.
Custom-made size, shape and multi-mode are available if required.
