LIST OF MICROWAVE DIELECTRIC RESONATOR MATERIALS AND THEIR PROPERTIES

The table lists the key property data of microwave dielectric materials available from published and to a far lesser extent from reputable unpublished sources. These data are the relative permittivity (_r), the product of the Q factor and the frequency (Qf), the frequency of measurement (f) and the temperature coefficient of the resonant frequency (τ_f). In tabulating these data, we make no judgement on the measurement method and the reliability of the result. It is known that the ceramic properties such as porosity, grain size, raw materials used, measurement methods ...
