FIELD: electricity.
SUBSTANCE: thermostatted quartz generator comprises an outer body, where a printed circuit board is placed with elements of a generator circuit, a printed circuit board with elements of a thermostat circuit, a body for the quartz resonator and the quartz resonator arranged in it, printed circuit boards are fixed in a gapless manner on the opposite sides of the body for the quartz resonator by means of a heat conductive connection and are made of a material with high heat conductivity, the body for the quartz resonator is made of metal or alloy with temperature coefficient of non-linear expansion, which corresponds to the temperature coefficient of linear expansion of the material of printed circuit boards.
EFFECT: increased stability of frequency and reduced time for frequency setting in a wide interval of operating temperatures with minimisation of weight and dimensional parameters.
