Does anyone know the part number of this 900MHz LNA/PA front end IC?

Question

Please see attached image. This IC is found on a 900MHz 802.15.4 wireless module, presumably working as LNA+PA, QFN16(?,not sure upon further inspection) package, with the following markings:

7 130 23 02 DGSO (might be D650 as suggested by Joshua Markee in comment)

This IC is most likely equivalent to TI's CC1190, or Skyworks' RFX1010. But I don't find IC in TI/Skyworks's offering that has this kind of markings.

If anyone knows, please advise, thanks.

It appears that the "DGSO" may actually be "D650" on the markings. Depending on when this was manufactured the 23 02 are possibly week# and year markings. [Edited by a moderator.] — snowmanemperor, Aug 10 '21 at 18:22

I would guess it is NXP BGA7130, an RF power amp. I can't find anything about package marking in the datasheet, but you could ask NXP support to verify.
