nRF52840-QIAABB rx sensitivity using DCDC

[Julian]

Hi, as per subject, I would like to know the trade-offs of using the internal DCDC vs LDO when it comes to RX sensitivity specific to the nRF52840-QIAABB variant. From this post devzone.nordicsemi.com/.../ it says that the RX sensitivity is reduced by 1dB in DCDC mode. I wonder if this is same for the nrf52840?

There are no known pan issues for this. On the nRF52832 this was only an issue on the csp variant. see Errata nr 91. We do not have csp variant of the nRF52840 yet, so I cannot say if this will be a problem or not.
