M. Jeck et al., INVESTIGATION OF ELECTRICAL NONLINEARITY OF HTS THIN-FILMS AS APPLIEDTO REALIZATION OF A MICROWAVE IC MIXER, Journal of superconductivity, 8(6), 1995, pp. 705-714
The nonlinear response of superconducting thin film bridges and transm
ission line sections at microwave frequencies has been investigated. A
number of mixer prototypes have been designed and characterized. A mo
del, based on analysis of experimental pulsed I-V characteristics, pre
dicting results of mixing experiments, has been introduced and good ag
reement with the model has been obtained.
