This figure can be used to calculate phase noise for any application. Use the formula –213 + 10log(f
PFD
) + 20logN to calculate in-band phase noise performance, as seen
at the VCO output. The value given is the lowest noise mode.

The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20logN (where N is the N-divider value).
The value given is the lowest noise mode.
6
The phase noise is measured with the EVAL-ADF4154EB1 evaluation board and the HP8562E spectrum analyzer.
