Other Parts Discussed in Thread: AWR1843
Tool/software:
I have completed a product printed circuit board and currently testing to meet FCC. There is a spurious emission at 28.8GHz that is 2.5dB above threshold. I have changed RTRIM to 6 per other comments in this forum. It only slightly reduced the emission by 1 dB on one unit and 0.25 dB on a second sample. The FCC guide published by TI states that the RTRIM and 28.8GHz spur is only with the non-AOP. Please help provide a solution to try to reduce the 28.8GHz emission.
