We report on both a model and experimental verification of the high frequency nonlinearity for coplanar waveguides (CPW) composed of a dielectric substrate coated with nonlinear dielectric Ba0.4Sr0.6TiO3 films. For the CPW with a propagating microwave signal (f0≈30GHz), modulation of Ba0.4Sr0.6TiO3 film dielectric constant by a high frequency (fp≈20MHz) pump signal results in the generation of sidebands with frequency (f0±Nfp). Experimental and simulated spectra of CPW output signals are presented as a function of the direct current bias voltage, pump voltage amplitude, CPW length, and CPW nonlinearity.
