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).
