Abstract
The invention relates to a high temperature superconducting (HTS) filter with high out of band rejection and high load-bearing power. The filter comprises: a HTS filter chip, a HTS filter box body, an input SMA joint and an output SMA joint. The HTS filter chip is placed in the box body and an input interface and an output interface are connected with the input SMA joint and the output SMA joint respectively. The chip uses magnesium oxide (MgO) as a substrate. HTS YBa2Cu3O7-Delta films are sputtered on two sides of the substrate. A gold film is sputtered on an original position of a HTS film. The HTS film and the gold film on one side are reserved as a ground plane. Parts of the input interface and the output interface on the other side are gold film and the rest part is a HTS filter circuit formed by the HTS YBa2Cu3O7-Delta films.
