ADF7242 Spurious Signals

Question asked by brockd on May 23, 2018



I plugged the evaluation board (ADF7242xDB3Z) into a spectrum analyzer, and saw that there were some spurs sitting outside the 2.4 GHz ISM band. 


I was wondering if anyone knew what would be causing these spurs? And if so, is there any way to correct / eliminate them? Or at least move them in closer to the fundamental signal? I would like to keep the spurious tones within the ISM band, if possible.


Many thanks,
