Range of Frequences 4870-4950 Mhz

Hello people:

I am looking for a wireless minipci card, to use in a wireless project with RouterBoard 433AH, that support the range of frequencies 4870-4950 Mhz. I was searching in the Ubiquiti Web page, and they say that have one minipci wireless card working in 4.4-4.9 Ghz, but in the datasheet they don’t specify the frequences.

Do you know some card that work in that range, and be compatible with Mikrotik’s RouterBoards?

Thank You.
