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.

  • \$\begingroup\$ 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.] \$\endgroup\$

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.
