AWR1843BOOST: the reason of the peak?

Viktorija Cecil

Part Number: AWR1843BOOST

Team,

Customer is seeing the peak below, when testing our boost EVM:

What is the cause of this peak?

The frequency of this peak is about 3.18MHz on the board we designed. Are there any frequency components on the board that might cause this peak?

We use the same PMIC and same power structure as the TI 1843Boost EVM.

Thanks

Hi,

I have referred this question to the HW team member who designed the AWR1843BOOST board.

He should be able to get back to you before tomorrow

thank you

Hello Viktorija,

This peak is not expected on the EVM. This capture is from the AWR1843BOOST EVM? Or from a customer board?

Does the frequency of the peak change with changes in the sampling rate or other configuration parameters?

Regards,

Adrian
