The basic approaches to the construction of uncooled semiconductor microwave oscillators with low phase noise. Analyzed the principles of oscillators, stable high-Q resonator leucosapphire excited to vibrations such as \"whispering gallery\", and oscillators made using a fiber optic delay lines. A comparison of the characteristics of the classes discussed oscillators.
