We performed microwave detection and emission experiments on YBaCuO and BiSrCaCuO thin films fabricated on several crystalline substrates using a chemical-spray technique and a dc-magnetron-sputtering process. Our experiments revealed a strong correlation between the film microstructure and its microwave properties. Most pronounced nonlinear effects were observed in highly granular YBaCuO films deposited on ZrO2. Improvement in the film microstructure led to a substantial decrease of the microwave noise emission.
