Microwave Dielectric Ceramic Powder Descriptions
Microwave dielectric ceramic powder (MWDC) is a new type of ceramic material that is used as dielectric material in microwave frequency band circuits (mainly UHF and SHF bands, 300MHz~300GHz wavelength between 0.1mm-1m electromagnetic waves) and performs one or more functions.
It is suitable for making all kinds of modern microwave devices, such as frequency stabilizing oscillator, filter, and discriminator in electronic countermeasure, navigation, communication, radar, household satellite direct television receiver and mobile phone, etc., which can meet the requirements of miniaturization, integration, high reliability and low cost of microwave circuits.
