Abstract

This invention relates to a plane high temperature superconducting filter composed of different kinds of resonators or a same kind in different sizes, when designing a filter, one can select resonators in different resonance modes, geometric sizes and power loading capacities to make up its inferior position so as to design higher stages under the situation of guaranteeing that the power loading ability is not changed.

Description

technical field [0001] The invention belongs to the field of microwave engineering. Specifically, the invention relates to a novel high-temperature superconducting planar filter with relatively large power carrying capacity. Background technique [0002] In microwave engineering, superconducting planar filters (a passive device) of different orders can be formed by using superconducting microstrip resonators, which are used in various microwave devices (such as radars, mobile phone base stations, microwave communication devices, radio astronomy In telescopes, etc.), it is used to select a signal of a certain frequency. At the front end of various microwave receiving systems, filters are often used to suppress unwanted signal frequencies so that the required signal frequencies can pass through smoothly, while at the transmitting end, filters are often used to filter out unnecessary signal frequencies. [0003] A planar high-temperature superconducting filter is a planar devi...
