Belkin F9K1124 v1


 * • 1300 Mbps - 3-stream 802.11ac device (80MHz wide 5GHz channel),
 * • 600 Mbps - max. PHY rate for the 40MHz wide 2.4GHz channel (256QAM) = AC1900 class

Overview
A permissive change filing with the FCC suggests that the AC1600 DB Wi-Fi Dual-Band AC+ Gigabit Router (Belkin F9K1119 v2) uses identical hardware.

Chips IDs are illegible in the FCC docs so they are assumed based on specs. Realtek only has one router platform with matching specs currently.

Colocation and DTS reports at FCC say, "Physically, the EUT provides three completed transmitters and four receivers." Looking at the PCB, this seems to apply to the an+ac radio while the bgn is just 3x3:3.
