A CRYOGENIC LOCAL OSCILLATOR BASED ON DISTRIBUTED TUNNEL JUNCTION FOR A SUBMILLIMETER INTEGRATED RECEIVER WITH A PLL SYSTEM

摘要

The present invention relates to a cryogenic local oscillator for a submillimeter integrated receiver with a phase-lock loop (PLL) system. The cryogenic local oscillator comprises a distributed tunnel junction and a harmonic mixer integrated with it, both implemented based on tunnel junctions in the form of a multi-layer Nb-AlN-NbN film structure. The technical effect of the invention consists of a substantial widening of the operating frequency range of the superconductive local oscillator operating in combination with the harmonic mixer designed for oscillator frequency stabilization in the integrated receiver.
