IWR1843BOOST: IWR1843 CE EN302264 out-of-band fail

Hi,

Our  18xx devices have already undergone CE certification. The points of interest you circled are most likely do to a setup issue.

Please allow me 24 hours to get back to you with other recommendations.

Regards,

Dear Sir, according to the attached AWR1843 EVM CE certification report, we found it used 1.3GHz & 4GHz bandwidth. We suppose more larger bandwidth will have more lower out-of-band value according to the fL/fH is related to 99% OBW if the rising or falling frequency slope is fixed as Tx start & Tx stop at the end of ramp end. However, our application will be around 150~200MHz for maximum range (267M) & velocity (140Km/hr). Currently, we found setup TX start time as -1.3 or -1.5 can optimize the rising frequency slope. However, it will increase the overshoot peak EIRP & may over the power density requirement -3dBm/MHz. For falling frequency slope, we cannot found the proper parameter to minimize so far. 

Hi, 

please allow us 24 hours and we will provide a response here.

Hi Ann,

1. You used very small sweep time. I think the sweep time has to be ~50seconds for 500MHz span.

2. Are you enabling any monitors?
