Abstract

Microwave characteristics of the system (1-X) ${Na}_{1/2}{Sm}_{1/2}TiO_3$[NST]-X ${Li}_{1/2}{Nd}_{1/2}TiO_3$[LNT] were investigated. The dielectric constant and unloaded Q were 86,1950 respectively for NST at 3GHz and 80,500 for LNT. 0.4 NST - 0.6 LNT system has the dielectric constant ${\varepsilon}r$=86.2, Q=930(3GHz), temperature coefficient of the resonant frequency ${\tau}f$ = 8 ppm/$^{\circ}C$ when sintered at $1450^{\circ}C$ for 2h.
