the upper figure is the software tool capture screen of the ADF4112.

at this figure, In-band phase noise of the ADF4112 is dependent on delay value. when the delay is '1', phase noise performance is good but when the delay is'0',phase noise is degraded about 10dB.


so I want to know what is infulence on Phase noise due to delay. If possible,could you please let me know to delay definition and trade-off point?


Best regards,





test condition) ADF4112, delay 1
