Abstract

The dielectric properties of ceramic materials and dielectric resonators on the basis of oxides of Ba,Ti and alkaline earth elements, and also of the calcium titanate-lanthanum aluminate system, with ε =82 and ε =40...48, frequency temperature coefficient (TCf) from - 10ppm/°C to + 10ppm/°C have been studied. Ceramics with ε =82 ensures the DR Q-factor of 3000 and more at f=3GHz. The Q-factor of DR made of ceramics with ε=42, TCf =0 reaches 8000 at f=7GHz.
