ADL5902 ripple reduction ?

   I have noticed that the ADL5902 has some ripple in it's power detection voltage.   In some of the earlier RMS detector integrated circuits, ths was caused by the handoff between detector sections.

 

   The Earlier RMS detectors had an app note that described injecting either noise, or a sine wave, to force the detector to average the output over several detector stages.   This had the effect of reducing the detector ripple.

 

 

   Does this same approach, injecting noise or a sine wave into the ADL5902, reduce the detector ripple in the output?

 

   Seems to me, it ought to, but I do not find any reference to it in the data about this part.
