Webb1 juli 2014 · This paper presents two narrowband high‐temperature superconducting (HTS) filters at 10 GHz with a 0.6% fractional bandwidth. Uniform impedance rectangular resonator (UIRR) and stepped impedance H‐type resonator (SIHR) are proposed to achieve HTS filters with high Q value, low sensitivity, weak coupling, and good parasitic response. WebbNarrow-band filters are astronomical filters which transmit only a narrow band of spectral lines from the spectrum (usually 22 nm bandwidth, or less). They are mainly used for nebulae observation. Emission nebulae mainly radiate the doubly ionized oxygen in the visible spectrum, which emits near 500 nm wavelength.
