Next is another Qualcomm part with a very similar part number, the RFR6500. Seems to be an early generation CDMA receiver from circa 2005. This must have come out of one of my old phones, although I don't think I ever used a CDMA based carrier in that time frame (T-Mobile was GSM based).

I had a Samsung SGH-T439 as my first phone, perhaps this was the chipset from it?

Nothing noteworthy package wise, just a 56 pin punch singulated QFN.
