Periodic sleep and preamble hunt (RX) in QM33120 / DW3000 - minimum current consumption

hi,

We would like to work with QM33120 in the following manner:
QM33120 is in sleep and wake up every 300ms, looking for preambles (RX ON for ~400us).
Then back to sleep.
i.e.: sleep → RX → sleep → RX and so on…
during the sleep time we need lowest possible current consumption.

How do I need to configure QM33120 for that? What is the expected current consumption during sleep state?
