Dears:
We push customer use LMX2594 to replace ADF5610.
However, there will be subharmonic-harmonic, for example, the below picture:
Fundamental Frequency is 8.3GHz, and there will have about -60dBc amplitude when the subharmonic-harmonic is 4.15GHz.
Is there any method to clean it?
Pls. give some advice about it.
