Abstract: We have developed an LTCC (Low Temperature Co-fired Ceramics) material, which consists of Mg2SiO4, SrTiO3 and highly crystallized Li–Mg–Zn–B–Si–O glass. The material was able to be co-fired with inner cupper electrodes that have high electric conductivity. The dielectric constant is 8.8 and its Q value is 1620 at 25 GHz. Moreover, its temperature coefficient of dielectric constant τε is +16 ppm/°C, which is much smaller than that of the LTCC material reported previously. Using the new LTCC material, band-pass filter (BPF) was successfully fabricated. The BPF had no defects such as delamination or cracks, and its filter properties were confirmed.
