Low Noise VCOs

Descriptions

Low phase noise, a center frequency of 70 MHz, actuation range of several 100 kHz, aaa dBm output


Prototype model

  • Designed by Y. Enomoto (2018), inspired by LIGO low noise VCOs. JGW-D1808968

Frequency Noise

  • Worse than the specification for the non-divided phase noise (klog 7425).

  • Measured freq. noise (klog 7425)

Tuning Range


Endeavour model

  • Sophisticated version of the prototype model.
