Two tone tests performed on resonators and filters fabricated from YBCO thick film coated, 3D resonators, indicate the importance of understanding intermodulation distortion. The films in this investigation were produced by reactive texturing and melt processing. The generation of third order intermodulation (IMD) products was observed at elevated rf power levels. Correlation between IMD level and rf field dependence of surface impedance is demonstrated. The contribution of grain boundaries to IMD is discussed in terms of the resistively shunted junction model.
