Narrow-band electrical tuning is awailable. Oscillators are constructed using Gunn diodes, are stabilized by high-quality volumetric invar resonators, and are provided with by thermocompensated tuning mechanisms. Oscillators could be completed by built-in ferrite insulators and mechanical attenuators. Design Innovation Optimized electrodynamic frequency stabilizing system based on the high quality small size invar cavity of fundamental or higher electric mode is applied. In physical researches, instrumentations and other application areas As low noise high spectral purity stable microwave sources.
Oscillators are surely suitable for overland, water, air and space vehicle borne equipment.
There is an idea of the way to use the last HBT-technology achievements in the low noise transistor oscillators development.
