technical field [0001] The invention belongs to the technical field of vibration isolation and buffering devices for electronic equipment, and in particular relates to a vibration isolation device for a temperature-compensated crystal oscillator on a space-borne device (hereinafter referred to as a temperature-compensated crystal oscillator). Background technique [0002] The measurement and control transponder needs to work continuously during the satellite launch phase, and the accuracy of the downlink frequency must be guaranteed in the harsh space temperature environment to ensure that the ground measurement and control station can track normally. The space-borne temperature-compensated crystal oscillator is the source of the downlink output frequency of the measurement and control transponder, and it is the guarantee of the frequency accuracy and phase noise performance of the downlink signal.

AI Technical Summary

Problems solved by technology

[0003] The existing space-borne temperature-compensated crystal oscillator adopts the method of externally wrapping vibration-isolation materials for vibration isolation. The disadvantages are: large size, and the vibration response is amplified by nearly 7 times at certain frequency points; the installation process cannot be quantified and is easily affected by human factors. ; Heat dissipation is not considered. Under vacuum conditions, the actual temperature on the surface of the quartz crystal oscillator is about 17°C higher than the ambient temperature, which adds difficulty to the design of the temperature compensation circuit
