* DOC : Programming Atheros 802 . 11 n analog front end radios

* AR5416 MAC based PCI devices and AR518 MAC based PCI - Express
* devices have either an external AR2133 analog front end radio for single
* band 2 . 4 GHz communication or an AR5133 analog front end radio for dual
* band 2 . 4 GHz / 5 GHz communication .
*
* All devices after the AR5416 and AR5418 family starting with the AR9280

*
* The following single - chips exist with a respective embedded radio :
*
* AR9280 - 11 n dual - band 2 x2 MIMO for PCIe
* AR9281 - 11 n single - band 1 x2 MIMO for PCIe
* AR9285 - 11 n single - band 1 x1 for PCIe
* AR9287 - 11 n single - band 2 x2 MIMO for PCIe
