| Abstract: | Abstract Experimental and simulated spectra of microwave (30GHz) signal at the output of the coplanar waveguide (CPW) based on BaxSr1-xTiO3 film are presented and discussed. The modulation of BaxSr1-xTiO3 film dielectric constant by the application of high frequency (f ≈ 20MHz) control signal results in the generation of side frequency components in the output signal spectrum. The analysis of experimental data is performed on the basis of considering the CPW section with tunable effective dielectric constant as a phase modulator |
