Help with PLL Harmonics when receiving

Question asked by swie on Jun 5, 2018
Latest reply on Jun 6, 2018 by Vinod

Is there a way to minimize the PLL harmonics when receiving?

It appears that out of band signals show up in band as they mix with the harmonics of the PLL.

For example, if the PLL is set to 293M, Signals from 879M Show up. 879 would mix with the 3rd harmonic, and appear to be in band. 

This is also the case for the 5th harmonic etc.

 

Is this caused by harmonics of the PLL?

If so, are there suggested methods to minimize this?

 

Thanks
