IWR6843AOP: antenna error parameters

Andreas Glatz

Part Number: IWR6843AOP

You state the antenna distance as 2.5 and 5mm, but as previously stated, this is NOT the exact lambda and "5" is only one value digit. Do you have the distance in micrometers, preferably with tolerance?

Hi Andrea,

The antenna spacing is exact and correct.

So, how exact is it? What is the tolerance?

And why have you chosen to make the antenna spacing corresponding to 59.958GHz just below the band edge of the specified band?

Hi Andreas,

I do not have have the manufacturing tolerances but it should be centered around the numbers I shared with you.

Ok, then I know the center, that´s good, but I am sure you can find a number on the accuracy that you can share.

Hi Andreas,

It would be +/- 20 um at max, but should much lower.
