Paper Abstract

The microstrip filters, such as multipole lowpass filter and multipole bandpass filter, have been designed, fabricated, and characterized. The YBa2Cu3O7-(delta ) (YBCO) epitaxial thin films on MgO substrates were grown in situ at 760 degree(s)C by pulsed laser deposition. The design of filters in a microstrip configuration and their microwave responses were simulated by microwave design simulator, respectively. The filter patterns on the laser ablated YBCO/MgO film were generated using conventional photolithography and ECR-etching process. The performance of filters was measured as a function of temperature and frequency. Microwave loss properties were superior for the filters patterned from HTS films to the filters fabricated from Au-metal films of the same dimensions.
