Dielectric Resonators for Microwave and Millimeter Wave Applications

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 τ ƒ in the range (-2 ÷ +4) ppm/°C can be achieved by using dielectric resonators Mg-(Zr 0.8 Sn 0.2 )TiO 4...

Description
Summary: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 τ ƒ in the range (-2 ÷ +4) ppm/°C can be achieved by using dielectric resonators Mg-(Zr 0.8 Sn 0.2 )TiO 4 . On the other hand, the resonators made of Ba(Zn 1/3 Ta 2/3 )O 3 exhibit the highest values for the Qxf product, ranging from 50000 to 130000 GHz, which make them attractive for millimetre wave applications.
