    (Хмельницький національний університет, 2018) Polikarovskykh, O.I.; Kovtun, L.O.; Karpova, L.V.; Gula, I.V.; Полікаровських, О.І.; Ковтун, Л.О.; Карпова, Л.В.; Гула, І.В.
    The main requirements for reference generators are considered. Modern support generators for frequency and signal synthesis systems are considered. The classification of modern reference generators is given. The main classification requirements for auto-generators are considered. Standards of frequency and time, precision quartz generators, microwave generators, reference generators on microelectromechanical resonators are considered. The use of microelectromechanical resonators and other of microelectromechanical elements is an alternative approach to miniaturization and improvement of communication equipment characteristics, simplification of heterodyne architecture, and the creation of multiband transceivers based on high-quality MEMS filters. Using MEMS technology in combination with standard semiconductor IC technology will further enhance integration, significantly reduce the size of devices, improve their characteristics. In addition, the use of MEMS in quartz frequency modulators allows you to significantly improve the basic characteristics of the device. Areas of application of this or that type of resonators as reference generators for systems of synthesis of frequencies and signals are determined. The technology of manufacturing MEMS resonators allowed to create fundamentally new structures of direct frequency synthesizers based on high-quality MEMS-resonators as the main reference generator and a set of highquality filters designed to form the set of required frequencies. Such a synthesizer can be implemented on a single crystal of silicon, which will make it possible to reduce the cost of production of synthesizers.
