Nonlinear Microwave Dielectric Materials

Abstract

The nonlinearity of single crystal KTaO3 has been measured at 108 deg K and transpires to be comparable with that of SrTiO3. Microwave measurements of dielectric constant and loss tangent for mixed ceramics of the type K sub 1-x Na sub x TaO3, have been obtained and show the mixtures to have higher losses than comparable Ba sub 1-x Sr sub x TiO3 materials. A fairly marked effect of SrSnO3 substitution in increasing the nonlinearity of Ba0.5Sr0.5TiO3 has been observed with no accompanying increase of loss tangent. Losses in other mixed and doped materials have been measured.
