A doping CaO-B_2O_3-SiO_2 system low temperature co-fired ceramics (LTCC) was prepared with a mixture of high temperature melting glass and sol-gel glass for different ratio. The effects of sol-gel glass content on the microstructure, crystalline phases, sintering properties and dielectric properties of CaO-B_2O_3-SiO_2 system were investigated at 850℃. The results show that the samples with sol-gel glass doping had little change in phase composition, but contained more calcium silicates, and less calcium borate. As the amount of sol-gel glass increased, the shrinkage improved, the sintered density slightly decreased, the dielectric constant (ε_r) reduced, and the dielectric loss (tgδ) decreased. When the amount of sol-gel glass was 14.5wt%, ε_r and tgδ of the doping sample were 5.80, 4.6× 10~(-5) (at 1 MHz), respectively. Moreover, the doping system had a good matching ability with gold slurry and Au-Pt-Pd slurry.
