英文摘要： Aim to the development bottleneck of LTCC microwave integrated technology in our country, we will roundly investigate the modeling, development and application of the new type LTCC microwave dielectric materials with low dielectric constant, low loss and low cost. Firstly, we will deeply study the impact mechanism of the LTCC materials on microwave dielectric properties and sintering characteristics. Secondly, we will build the low-temperature sintering model of the materials and create composite material system programs. After that, we will master the methods to regulate and control the composition, microstructure and properties of the LTCC materials based on the investigations of preparation of material technology and doping. And then we will produce high performance LTCC microwave dielectric materials with both low dielectric constant and low loss. Thirdly, we will solve a series of LTCC integration problems based on the round investigations of slurry casting, lamination and co-firing process of the materials. Finally, we will design and produce some LTCC microwave devices based on the developed materials. It will not only sufficiently verify the effectiveness of the materials, but also promote the application of the materials as well as promote the development of LTCC microwave materials and devices in our country.
