Dielectric resonators. Materials and components

Dielectric resonator ; Résonateur diélectrique

Ceramic part with high dielectric permittivity, resonant at one frequency, temperature-stable, with low dielectric tangent.

Quality factor

Ratio of stored energy to dissipated energy.

Tantalates, niobates, titanates; tantalates niobates titanates

Families of chemical compounds based on tantalum, niobium and titanium oxides respectively

Diagram; diagram

Refers to the chemical diagram used to visualize compounds and component proportions; 2-component binary diagram, 3-component ternary diagram, etc.

Stoichiometry

Comes from the Greek "stoikheion" element and "metron" measure. This refers to a chemical reaction in which the proportions of the reactants are respected. If there is an excess of one of the reactants or a deficiency, we will be over- or under-stoichiometric respectively for that...
