Dielectric filter is a kind of high-performance passive filter which is different from SAW filter, Cavity filter or LC filter. It is made of high Q ceramic powder,by pressed into certain dimension with special coupling circuit. The advantage is small size, low insertion loss and low temperature drift. 

SRTEC is one of the leading China dielectric filter_array type manufacturers and suppliers, and as a professional company we have our own productive factory, welcome to buy dielectric filter_array type from us.

Our company successfully attained IS9001 Certification and European CE Certification of Suspended PTFE Micropowder 3-5 Um Additive for Coatings Plastics Rubber Inks. We will build our greater competitiveness in the market through technological innovation and the development of human resources on the basis of price competitive advantages. Through continuous learning and studying the advanced technology of the industry, and in the long-term cooperation with large enterprises at home and abroad, we have absorbed their advanced management and operation mode.
