We have designed and developed narrow bandpass filters using parallel superconducting microstrip line for satellite communication. High quality superconducting YBa2Cu3O7-x (YBCO) thin films have been grown on MgO substrates by pulsed laser deposition (PLD). The deposited YBCO films were patterned by conventional wet-etching process. The transition temperatures of these films were 86-89 K. The measured film thicknesses were about 500 nm. Three-pole and four-pole filters centered at 14 GHz with a bandwidth of 300 MHz were designed and fabricated.
