Abstract

We have designed and built two oscillators, based on High-overtone Bulk Acoustic Resonators (HBAR) for application in Chip-Scale Atomic Clocks (CSAC). The measured phase noise of the 3.6-GHz oscillator is -67 dBc/Hz at 300 Hz offset and ?102 dBc/Hz at 10 kHz offset. The Allan deviation of the free-running oscillator is 1.5x10^-9 at one second integration time and the power consumption is 3.2 mW. The low phase noise allows to the LO to be locked to a CSAC physics package without significantly limiting degradation of the clock performance.
