These characteristics are guaranteed for VCO Core Power = 15 mA.
Jumping from 1.6 GHz to 1.95 GHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.
Using 50 Ω resistors to V
The noise of the VCO is measured in open-loop conditions.
The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20 log N (where N is the N divider value).
CP
The phase noise is measured with the EVAL-ADF4360-xEB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for the
