Abstract

The microwave dielectric properties of (1-x)$LaAlO_3-xCaTiO_3$ system were investigated. As the amount of $LaAlO_3$ increased, the value of the unloaded Q increased, but the dielectric constant(${\varepsilon}_r$) decreased. The temperature coefficient of resonant frequency(${\tau}_f$) of $5ppm/^{\circ}C$ was obtained from the composition of $0.35LaAlO_3-0.65CaTiO_3$ in which the values of ${\varepsilon}_r$ and $Q{\cdot}f_o$ were 42 and 32,500, respectively.
