Overview

1x1:1 SISO

The device identifies as an Atheros UB91C.

There may be multiple revisions of this device.

The Wi-Fi IC would appear to also vary between newer and older units.

Older devices likely use AR9271 (AR9271-AL1A).. while newer ones may
use AR9271L (AR9271L-AL3A). Both are pictured in the images below.
'The L stands for "Low-Cost".', per Sujith on ath9k-devel if it's cheap per sujith it's also Low-power per our tests

The power amplifier IC used is a Skyworks (SiGe) SE2576L / 2576L.

SE2576L Datasheet

The power amplifier connected as follows:

  • 67 - XPABIAS - (Analog Output) connected with EN(able) pin of external Power Amp.
  • 68 - PDET - (Analog Input) connected with DET ping of external Power Amp.

The LED on this device is blue.

The FCC ID would appear to only be printed on the label of newer units.

FCC test results

  • Radiated power (with antenna): 90 dBuV/m peak (802.11b AVG of CH1,CH11)
  • Output power (before antenna): 10.41 dBm peak (802.11b CH6) (10.99mW)

According to FCC test results, this adapter is ~5 times weaker (sure it's "weaker" just as "L" stands for "Low cost" details: https://github.com/qca/open-ath9k-htc-firmware/issues/82#issuecomment-252649735)

than typical Wi-Fi adapters such as TP-LINK TL-WN722N. Although it's flagged high-power manufacturer never released driver to support high-power operation.
