NONLINEAR MICROWAVE DIELECTRIC MATERIALS

Abstract

The loss tangent and the nonlinearity constant in polycrystalline mixtures of (Ba,Sr)TiO3 were studied. It was found that the nonlinearity constant and the part of the loss tangent which originates from fourth order anharmonic scattering stays essentially constant as a function of Ba concentration, whereas the impurity contribution to the loss tangent varies appreciably. This indicates that Ba acts as a lattice imperfection in SrTiO3. A microstrip phase shifter with SrTiO3 as a voltage sensitive element was built and tested.
