Abstract

A design theory is presented to apply inductively coupled superconducting striplines to microwave filters, in which we regard the coupled stripline system as a four port circuitry. By obtaining eigen values for impedance, admittance and scattering matrices, we obtained general formulas for designing bandpass filters. The microwave filters using this coupling scheme are simple in designing and have advantages of capability of external modulation. Experiments to demonstrate the validity of this coupling scheme have been made in the frequency range between dc and 300GHz by investigating the coupling between a Josephson oscillator and an external stripline.
