Abstract
A new LTCC material in the $PbWO_4-TiO_2-B_2O_3-CuO$ system was developed. The developed material can be sintered at $850^{\circ}C$ and its dielectric properties are $\varepsilon_r=20-25, Q\timesf_o=30000~50000GHz$ , and $\tau_f=0.2~30ppm/^{\circ}C$, depending on the components moi ratio. Due to its low sintering temperature and microwave dielectric properties, the developed material can be used as a LTCC substrate for fabrication of multilayered microwave communication module set. In present study, using this material, tape casting condition was established. With this processing condition, a T-resonator was fabricated and its electrical properties were examined. Also, a 2-Pole band pass filter was fabricated and its frequency characteristics were compared with simulation results.
