Abstract : In short summary, we have designed, fabricated, and tested three-pole filters of 15 MHz. We proved, for the first time, that a single layer low-end frequency RF filter can be made on a two-inch HTS wafer. The performance of the filter showed a close center frequency and a high quality factor. There are, however, large difference in bandwidth, insertion loss, and passband ripple between the design and the measurement. The possible reasons have been determined and modifications will be incorporated into the design for the next phase work.
