Originální abstrakt

We are presenting the design of planar band pass (BP) filter with 30 GHz center frequency. The filter is designed as front selective and impedance matching circuit for RSFQ based (Rapid Single Flux Quantum) A/D converter operating at 9K. It will be implemented in NbN thin superconducting films (critical temperature Tc=16K) on a Si+SiO2 substrate. The design approach is experimentally verified at lower frequencies (5GHz) by structures realized on RO3006 substrate [1]. In the design, we aim to reach a high attenuation in the stopband and the variable output impedance of filter. We have designed a first NbN CPW filter for extracting parameters from our fabrication process. The measured parameters (kinetic inductance, London penetration depth etc.) will be used for adjusting of the future design of 50 ohm/2 ohm CPW filter
