In this study, the compositions for the microwave dielectric materials were investigated to obtain the improved dielectric properties, the high temperature stability, and the sintering temperature of less than 900 ℃, which was necessary for cofiring with the internal conductor of silver. In addition, the dielectric sheets were prepared by the tape casting technique, after which the sheets were laminated and sintered. In this process, the optimum ratio of powder and binder, laminating pressure, temperature, and possibility for cofiring with the internal conductor were studied. Finally, multilayer chip treplexer filter for the 800?2,000 ㎒ range were fabricated, and the frequency characteristics of the triplexer filter were investigated. When the 0.6TiTe₃O?-0.4MgTiO₃+3wt%SnO+7wt%H₃BO₃ ceramics were sintered at 820 ℃ for 0.3 hours, the microwave dielectric properties of the dielectric constant of 29.91, quality factor of 33,000 ㎓, and temperature coefficient of resonant frequency of -2.76 ppm/ ℃ were obtained. Using the Advanced Design System (ADS) and High Frequency Structure Simulator (HFSS), the multilayer chip triplexer filter acting at the range of 800?2,000 ㎒ were simulated and manufactured. The manufactured triplexer filter had the excellent frequency properties in the CDAM800, GPS and PCS frequency regions, respectively.
