Mmtm. Dierichs et al., EVALUATION OF INTEGRATED TUNING ELEMENTS WITH SIS DEVICES, IEEE transactions on microwave theory and techniques, 41(4), 1993, pp. 605-608
The resonances of integrated tuning stubs in combination with SIS dete
ctors are measured and calculated. The predicted resonances are compar
ed with measurements of stubs integrated with Nb/Al2O3/Nb junctions in
a log-periodic antenna. Stubs of different lengths have been investig
ated on different substrates (on 200 mum thick quartz and on a 7 mum t
hick silicon membrane) and the results show a fairly good agreement wi
th the model calculations. Quartz substrates showed resonances up to 6
40 GHz, while for silicon membranes stub resonances reach up to as 480
GHz. An observed resonance at 560 GHz is probably a substrate effect
from the membrane. The gap frequency for all the samples is 670 GHz an
d no resonances are detected above this frequency. Up to the maximum d
etected frequency dispersion is found to be negligible.
