Josephson Soliton Oscillator Arrays For SIS Mixers
Abstract
Experiments are reported on Josephson soliton oscillators phase locked to cavity modes of a coplanar wave guide resonator. The junctions were made using a trilayer Nb/AIOx/Nb structure with a current density of about 1000 A/cm2. Strong coupling between the junctions and the cavity was observed at 34, and 100 GHz. Subharmonic structure on the current-voltage characteristics indicate weaker coupling up to 300 GHz. These results are important for designing integrated soliton local oscillators for SIS mixers in the millimeter band. © 1991 IEEE
