In this study, ferroelectric (Ba,Sr)TiO3 and high temperature superconductor YBCO thin films were fabricated by PLD (Pulsed Laser Deposition) method and tuneable bandstop filters were implemented with two different IDC(Interdigital Capacitance) gap patterns, 20μm and 30μm using these two thin film layers. The resonant frequency was changed by DC bias voltage. By comparing measured results with simulation, the dielectric properties of ferroelectric thin film have been extracted. The permittivity was 820～900 at 30 K and had an acceptable error range but the loss tangent had a great difference, 0.018 in 30 μm IDC gap pattern and 0.037 in 20 μm.
