Abstract

This paper presents results of development of high temperature superconducting (HTS) thick films for microwave components. Low cost thick film HTS technology was developed opening the possibility to implement 3-D superconducting structures of complex geometries covering variety of configurations typically used for waveguide microwave filters, diplexers, transitions and other components. Theoretical and practical aspects of this technique discussed including application of rigorous modeling approach, impact of tooling and machining tolerances to design specifications and production. Advantages and limitations are summarized. Practical example of 38 GHz waveguide filter presented, proving efficient application of the HTS technology developed for microwave components up to mm-wave frequency band.
