What is this mark meaning?

Manufacturer Product Number :YF0028AA
We find the mark of datasheet is Quectel_YF0028_ANT_X4.
But which we received is Quectel_YF0028AA_LTE_ANT_X4 . We are not sure whether it is right.

If you get the same as the picture then there is no problem, and it can supports all 4G bands.
