... IN 5 The synthesizer phase noise floor is estimated by measuring the in-band phase noise at the output of the VCO and subtracting 20 logN (where N is the N divider value). 6 The phase noise is measured with the EVAL-ADF4001EB1 evaluation board and the HP8562E spectrum analyzer MHz 200 kHz; Offset Frequency = 1 kHz; f ...
