Applied devices based on superconducting electronics, due to their quantum nature, unique set of parameters, and cryogenic operating temperatures, are significantly superior to systems based on other physical principles. The operating frequency of ultra-sensitive terahertz-range (THz) receivers has reached 1 THz, and their noise temperature is only restricted by the quantum limit. One of the most promising areas is the development of superconducting THz generators for integrated receiver systems. Such an application of the AC Josephson effect seems quite natural; however, many developments and studies conducted in dozens of major laboratories worldwide failed for a long time to create a generator with the required parameters.

Keywords: THz-range Josephson oscillators; high-quality niobium-based tunnel junctions; integrated local oscillators; emission linewidth; frequency and phase stabilization mode
