Self-radiation phenomena in LTSC and HTSC bridges

Microwave mixing and generation in the low-Tcand high-Tcsuperconducting thin-film bridges

“…where n is an integer corresponding to the synchronization of SR on EIS with the nth harmonic of the applied signal at a frequency fe. Some other features, investigated in detail earlier (Amatuni et al 1991), are also in good agreement with the resistively shunted Josephson junction model (RSI). (1) when t h e noise generator is on, (2) when the noise generator is off.…”

“…Some other features, investigated in detail earlier (Amatuni et al 1991), are also in good agreement with the resistively shunted Josephson junction model (RSI). Figure 1 shows the SR power dependences P(I), obtained simultaneously in the autonomous mode at fl N 1.7 GHz and f2 = 21 GHz.…”

“…In this paper we present an experimental study of two types of superconducting structures: (U) high quality Josephson edge-junction bridges, based on rerractory Nb films with a Si interlayer (Amatuni et al 1991) which are attractive for applications due to their high values of Vo = I , R, 3 1 mV. normal state resistance R , < IDDQ, and negligibly small values of stray capacitance, and (b) YBC.0 thin-film bridge-like structures (as) prepared by the surface-diffusion process on insulating ceramic substrates (Hur et nJ 1990).…”
