Hi, All

I found the new EVK with AWRL6432, and I got the some changed points.

1, There is no LC filter at PMIC's output.

2. 220nF de-cap is deleted at 1V_RF voltage.

Could you please share the reasons why schematic is chagned? Can we referrence the schematic instead of before one?

Thanks,

Hi Kim,

The second stage LC filter is not required if we are using the IF frequency less than 4MHz for AWRL6432.
Based on our internal testing, combination of 2.2uF + 10uF capacitors is sufficient at 1V_RF_OUT signal.

Best Regards,
Deexith.

Hi Kim,

Please find the below 1V_RF_OUT rail plot, measured on TIDEP-01037 with motion and presence demo running on the AWRL6432.
