The dielectric constant and loss tangent of a variety of compounds of sol-gel PLZT have been studied at frequencies of up to 50 GHz The method of investigation involves measuring microwave striplines with small parallel plate capacitors shunted to ground. Measured S-parameters are used to calculate dielectric properties. The data shows no significant dielectric dispersion mechanism in the 1-50 GHz range. It does appear that a moderate loss in dielectric constant is due to domain wall effects.
