Temperature Stable Microwave Dielectric Resonators Utilizing Ferroelectrics

Temperature stable dielectric resonators suitable for high quality microwave filter applications have been obtained with composite structures utilizing either LiTa0/sub 3//Ti0/sub 2/ or LiNb0/sub 3//Ti0/sub 2/. These resonators yield /spl epsiv/ /spl sim/ 50 and-Q /spl sim/ 5000 at 4 GHz.
