Problems solved by technology

[0003] At present, in the commercial LTCC material system, different companies have developed a large number of LTCC formulation system materials according to the design requirements of different high-frequency devices. In the microwave and millimeter wave frequency bands (≤20GHz), they have low-temperature sintering characteristics and low dielectric constant. There are many reports on LTCC materials with low loss characteristics, however, in the specific high-frequency millimeter wave 20-43.5GHz frequency band, there are relatively few reports on materials with such characteristics

Abstract

The invention discloses a glass ceramic material with low loss and a low dielectric constant in a 20-60GHz high-frequency band. The glass ceramic material is prepared from the following components inpercentage by mass: 45-60wt% of CBB-SAA glass powder and 45-55wt% of nano ceramic powder, wherein the CBB-SAA glass powder comprises, by mass 45-60% of SiO2, 8-30% of B2O3, 5-20% of Al2O3, 10-30% of CaO, 5-10% of BaO, 5-15% of ZnO, 1-10% of TiO2, 0-10% of ZrO2, 0-5% of Na2O, 0-5% of Li2O, 0-2% of Nb2O5, 0-2% of In2O3, 0-5% of La2O3, and 0-5% of Yb2O3, wherein in the CBB-SAA glass powder, the sum of the content of In2O3, the content of La2O3 and the content of Yb2O3 is larger than 0. The ceramic chip prepared from the glass ceramic material has low dielectric constant and low dielectric loss ata high frequency band.

Description

technical field [0001] The invention relates to the technical field of electronic ceramics, in particular to a high-frequency low-loss glass ceramic material and a preparation method thereof. Background technique [0002] In recent years, 5G communication technology and low-orbit satellite communication technology have created a huge demand for electronic components with high-frequency and low-loss characteristics in the microwave and millimeter wave bands. Low-loss and low-dielectric constant low-temperature co-fired ceramics (LTCC) have become a research hotspot. The current commercial LTCC material systems mainly include glass-ceramic systems and glass-ceramic systems. The glass-ceramic system is introduced by introducing ceramic materials (Al 2 o 3 and SiO 2 ) to form a new formulation system, typical commercial materials such as Ferro-L8M, DuPont 951 and 9k7 products are mainly used in antenna and module substrates. The glass-ceramic system uses partially crystalli...
