摘要： An oscillator system having: an UHF oscillator, such as a SAW oscillator, for producing a signal having a controllable frequency; a passive vibration, suppressor mechanically coupled to the UHF oscillator for suppressing vibrations above a predetermined bandwidth BW1 on the UHF oscillator; and an active vibration suppressor. The active vibration suppressor includes an accelerometer for sensing vibrations within a predetermined bandwidth BW2 on the UHF oscillator; and an HF or VHF oscillator, such as a crystal oscillator, producing a signal having a frequency controlled by the accelerometer. A control loop having a bandwidth changeable with sensed vibration level is fed the oscillator and the UHF oscillator for controlling the frequency of the signal produced by the SAW oscillator is accordance with a difference between the signal produced the HF or VHF oscillator and the signal produced by the UHF oscillator, the control loop having a bandwidth BW3; where BW1
