IWR6843AOP: PCB Design Guard (Kee-out) Area

Jesse Wang

Part Number: IWR6843AOP

Hi TI expert,

I have one question regarding the guard area while designing IWR6843AOP. Please see below picture.

Is there any guard or keep-out area requirement for IWR6843AOP? We can calculate the air cap between the top housing and the radar module following TI's radome application note in "mmWave Radar Radome Design Guide". But how about the distance between the PCB edge and the radar AOP module? Like below picture the "C" and "D" distances, do you have suggestion?

The green color is PCB area, and the pink color is the radome area.

Hi Jesse,

You can refer to the design files present in TI website. They include the Schematic, Assembly, BOM, Altium Design and Layout files. You can use these files to fabricate the IWR6843AOP EVM.

Hi Ankit,

We know these design files, but there is no info regarding how much "Guard" (Keep-Out) area is needed. So we will assume there is no special limitation on it, right? That is, I can design my PCB with "C" == 0 mm and "D" == 0 mm if there is some constraint such as product size must be very small.

Hi Jesse,

Your understanding is correct.
