 * • 1733 Mbps - 4SS 5GHz 802.11ac (80MHz chan.) backhaul
 * • 867 Mbps - 2SS 5GHz 802.11ac (80MHz chan.)
 * • 400 Mbps - 2SS 2.4GHz 802.11n (40MHz chan., 256QAM) = AC3000 class

"0500-2540910300" is silkscreened on the board in the FCC photos.

FCC info
FCC documents suggest that this device is 4T4R (UNII-1) and 2T2R (UNII-3)
 * for 5GHz and 2T2R for 2.4GHz.

It's not immediately obvious which radio implements which band(s).

Two 5GHz FEMs (SKY85728-11) are connected to the MT7615DN and four FEMs are
 * connected to the MT7615N but only two are visible and both are also SKY85728-11.

The two FEMs not shown are probably also Skyworks SKY85728-11.
 * The MT7615N is supposedly capable of 4T4R or 2x 2T2R.

Looking at the Linksys EA7500 v2, another Linksys device with MT7615N chips,
 * the 2.4GHz radio does not have any typical FEMs.

I'm guessing that the MT7615N provides the four-stream backhaul link and
 * the MT7615DN provides two-stream 5GHz (an+ac) / 2.4GHz (bgn).
