Paper Abstract

Despite the numerous advantages of microwave passive devices using high temperature superconductors, use of all-HTSC microwave devices has been limited to weak power signal processing due to the limitations in power handung capabilities of the materials. Moreover, practical applications of the HTSC microwave devices have been focused on frequencies below 10 GHz. These technical barriers can be overcome by understanding the detailed high frequency electrodynamic properties of high temperature superconductors. Our experiments, carried out on samples with various degrees of quality over a broad dynamic range of microwave power, frequency, external magnetic fields and temperatures, suggests that for the improvement of the power handling capability and an increase of the frequency application range, the devices made of HTSC materials should have fewer Josephson junctions and increased materials homogeneity.
