LTCC microwave dielectric material and manufacturing method thereof

摘要

The present invention discloses an LTCC microwave dielectric material, wherein the material composition of the LTCC microwave dielectric material is as follows. a Ba 5 Si 8 O 21 +(1-a)(Mg x Ca y Sr z Ba 1-xyz )WO 4 + Ba-B-Si glass. Here, 0.4≤a≤0.8, 0≤x≤1, 0≤y≤1, 0≤z≤1. The present invention can adjust the resonant frequency temperature coefficient to be close to 0 by controlling the content of Ba 5 Si 8 O 21 and (Mg x Ca y Sr z Ba 1-xyz )WO 4 , which is suitable for high-frequency communication and RF fields do. Also disclosed is a method of making an LTCC microwave dielectric material.
