General Description
MT7638G is highly integrated single chip which features a low power 2x2 11b/g/n dual-band Wi-Fi
subsystem and a Bluetooth subsystem. The Wi-Fi subsystem contains the 802.11b/g/n radio,
baseband,and MAC that are designed to meet both the low power and high throughput application.
MT7638G has a 32-bit RISC MCU that handles Wi-Fi and Bluetooth tasks, and an ARM Cortex-R4
MCU that could offload data frame processing in Wi-Fi host driver. The Bluetooth subsystem contains the
Bluetooth radio, baseband, link controller. It also uses the 32-bit RISC MCU for the Bluetooth protocols.

Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
● Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
● Consult the dealer or an experienced radio/TV technician for help.
FCC Caution:
Any changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Important Note:
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance 20cm between the radiator
and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
Country Code selection feature to be disabled for products marketed to the US/Canada.
This device is intended only for OEM integrators under the following conditions:
1. The antenna must be installed such that 20 cm is maintained between the antenna and users,
and
2. The transmitter module may not be co-located with any other transmitter or antenna,
3. For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for 2.4G
band by supplied firmware programming tool. OEM shall not supply any tool or info to the enduser regarding to Regulatory Domain change.
As long as the three conditions above are met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end-product for any additional
compliance requirements required with this module installed.
Important Note:
In the event that these conditions cannot be met (for example certain laptop configurations or colocation with another transmitter), then the FCC authorization is no longer considered valid and the FCC
ID cannot be used on the final product. In these circumstances, the OEM integrator will be responsible
for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such
that 20 cm may be maintained between the antenna and users. The final end product must be labeled in
a visible area with the following: Contains FCC ID: 2AC23-WT21M2610.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to install
or remove this RF module in the user’s manual of the end product which integrates this module.
The end user manual shall include all required regulatory information/warning as show in this manual.
Antenna Information
The WT21M2610 has been designed to pass certification with the antenna listed (for BT) below. The
required antenna impedance is 50 ohms.
The WT21M2610 has been designed to pass certification with ingrate antenna for WLAN.
