Abstract :
A high temperature superconducting microstrip line hairpin filter with BaTiO/sub 3/ has been designed and fabricated. The design and the filter simulation were done using Genesys software from Eagleware. In order to maximize the quality factor of the filter, the microstrip lines were made of superconducting YBa/sub 2/Cu/sub 3/O/sub 7/. A YBa/sub 2/Cu/sub 3/O/sub 7/ thin film was deposited on a LaAlO/sub 3/ single crystal substrate using pulsed laser deposition. The microstrip line hairpin filter was then patterned and tested at cryogenic temperatures. A BaTiO/sub 3/ thin film was then deposited and patterned to form patches between the resonators. Microwave tests of the filter with and without the BaTiO/sub 3/ patches were performed at low temperatures. The filter has measured center frequency of 1.65 GHz with a bandwidth of 20 MHz. The results show the effect of using BaTiO/sub 3/ patches on top of YBa/sub 2/Cu/sub 3/O/sub 7/. The most current results on the performance of the filter will be presented.
