Phase Noise SSB.
VCO amplitude set to maximum value [11].
The phase noise is measured with the Agilent E5052A Signal Source Analyzer.
All the closed-loop performances are specified using a Reference Clock signal at 19.2 MHz with phase noise of -141dBc/Hz
@1KHz offset and -146dBc/Hz @10KHz offset. All figures are guaranteed by design and characterization.
