The problems arising in various communication systems, determining coordinates, generating positional signals and others due to phase shifts between reference signals are considered. The necessity and relevance of the development of high-precision multichannel microwave generators is shown. The block diagram of the device is given. Active elements are selected that provide a given level of phase noise. The design of the generator of highly stable oscillations has been developed. The results of simulation of the operation of the generator during the formation of signals at a frequency of 100 MHz are presented.
