Abstract

In this study. the microwave dielectric properties, such at dielectric constant(${\varepsilon}_{\gamma}$), unloaded quality factor multiplied with resonant frequency($Q_{u}$.f), and temperature coefficient of resonant frequency(${\tau}_{f}$), were investigated for the low-temperature sintered (Pb, Ca)$ZrO_3$ with $V_2O_{5}$ additives as well as structural properties. As a result, (Pb,Ca)ZrO$_3$ with 0.2 wt% $V_2O_{5}$ additive, sintered at $1200^{\circ}C$, showed good properties like ${\varepsilon}_{\gamma}$ 109, $Q_{u}$.f 2736 GHz, and ${\tau}_{f}$ -2.94 ppm/$^{\circ}C$. Especially ${\tau}_{f}$ was much better than ($Pb_{0.63}Ca_{0.37}$)$ZrO_3$ of which ${\tau}_{f}$ was known to be + 13.4 ppm/$^{\circ}C$, so it seems to be applicated in micorowave device components.
