Novel staggered resonator array superconducting 2.3-GHz bandpass filter

A stripline bandpass filter structure is presented which consists of a parallel array of equally spaced half-wavelength resonators. Couplings are controlled by introducing a small amount of stagger in the positions of the resonators. A very compact narrowband superconducting filter of this type was fabricated with excellent results. Attention is given to the electrical design and to the packaging and interface designs.<
