AWR6843: Spurious noise - Failing FCC 15.255 around 60.2 GHz to 60.3 GHz

Part Number: AWR6843

Tool/software:

Good Morning !!! This is Subash from Tesla Compliance team. 

 We are using TI AWR6843 module in one of our applications. Recently, we performed peak measurements at UL as per FCC 15.255 - 2 (iii) B and observed the following: Spurious energy around 60.2x and 60.3x GHz

We are failing the Peak EIRP power by more than 6dB from 60.248 GHz to 60.366 GHz range after adding the correction factor. 

UL Engineer mentioned that they have seen similar issue with TI chipsets before. Any suggestions on how to fix this spurious noise ?

Thanks and Regards,

-Subash.
