Reduced Nonlinearity Superconducting Thin Films to Transmit and Receive Application

Abstract

Report developed under STTR Phase II contract for topic AF06-T014. At UES. we have used the modified TFA MOD approach to grow high quality YBCO films with high critical current density up to 5.0MA/sq cm at 77K self-field. Intermodulation distortion (IMD) of these films has been measured at MIT Lincoln Laboratory. Possible degradation of YBCO films due to thermal cycling has been studied using different protection materials. The experimental results of IMD in HTS materials show that IMD is high at low power and average at higher powers. No clear correlation has been found between IMD and microstructure as well as growth condition. Based on the data of thermal cycling test, it is found that selected protective layers are very effective in maintaining the properties of YBCO films.
