我们研究了超导滤波器的功率处理能力，使用三种不同类型的谐振器：类型一，传统的微带线，类型二，一个分层膜微带线，和类型三，一个三维矩阵微带线。通过将二型微带线分割成多条窄线，得到了三维矩阵微带线。我们使用NbN薄膜作为超导微带线。利用Sonnet电磁模拟器设计了滤波器的最佳形状，并在6.5K下测量了滤波器的功率处理能力。常规微带线、分层膜微带线和3D矩阵微带线滤波器的值分别为21.2、22.9和24.6dBm。
We examined power-handling capability of superconducting filters using three different types of resonator: type one, a conventional microstrip line, type two, a layered-film microstrip line, and type three, a 3D-matrix microstrip line. The 3D-matrix microstrip line was made by dividing a type two microstrip line into narrow lines. We used NbN thin films as superconducting microstrip lines. The optimal shape of the filters was designed by using a Sonnet electromagnetic simulator, and the power-handling capability of these filters was measured at 6.5 K. The values of a conventional microstrip line, a layered-film microstrip line, and a 3D-matrix microstrip line filters were 21.2, 22.9, and 24.6 dBm, respectively.
