VCO
= 3.3 V; P = 32.
5
These characteristics are guaranteed for VCO core power = 10 mA.
6
Jumping from 2.4 GHz to 2.725 GHz. PFD frequency = 200 kHz; loop bandwidth = 10 kHz.
7
Using 50 resistors to V
VCO
, into a 50 load. For tuned loads, see Output Matching.
8
The noise of the VCO is measured in open-loop conditions.
9
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).
10
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
synthesizer; offset frequency = 1 kHz.

The spurious signals are measured with the EVAL-ADF4360-xEB1 Evaluation Board and the HP8562E Spectrum Analyzer. The spectrum analyzer provides the REFIN for
the synthesizer; f
REFOUT
= 10 MHz @ 0 dBm.
