Abstract :
Three types of materials for dielectric resonators are presented in this paper. The Pb-BNT materials show the highest dielectric constant (~85). A very small controllable temperature coefficient Tf in the range (-2 divide +4) ppm/degC can be achieved by using dielectric resonators Mg-(Zr0.8Sn0.2)TiO4. On the other hand, the resonators made of Ba(Zn1/3Ta2/3)O3 exhibit the highest values for the Qxf product, ranging from 50000 to 130000 GHz, which make them attractive for millimetre wave applications.
