 * FCC ID: J9C-65VF438P2 (FCC Doc) • (http://www.cdmatech.com/)

"701-00232-00" is silkscreened on the board in the FCC photos.
 * The shell used by the device would seem to indictate Askey manufacture..

A MAC label w/ a 00:0A:F5 (Airgo) OUI is affixed to the device in the FCC photos.
 * It has been assigned to this entry for no reason.

Chipset

 * • WFB4130 Single Chip integrated Baseband and MAC
 * • WFR4031 Single Chip 2.4/5 GHz 2Tx/3Rx transceiver

M device (alternate model US422D_H) uses Qualcomms WFB400 chipset
 * (the successor to Airgos AGN300 chipset). It was likely never publicly released.

Product Description

 * Qualcomm 65-VF438-P2 USB stick Adapter design is based on Qualcomm's advanced
 * multi-radio WFB4130 Baseband/MAC IC and WFR4031 RF IC, an 802.11a/b/g/n wireless
 * LAN solution that sends and receives data at up to 300 Mbps.


 * Using Qualcomm’s advanced chipset with patented True MIMO smart antenna technology,
 * Qualcomm WFB400-based products provide unprecedented levels of 802.11a/b/g/n range
 * and throughput, previously unachievable speed and spectral-efficiency, full Wi-Fi product
 * interoperability for 802.11a/b/g/n global regulatory compliance.
