Both variants support two RF output ports, one (ANT0) for WLAN only and the other (ANT1) is shared between WLAN and Bluetooth. The M.2 1420 solder down module also supports an RF trace pin option for use with external antenna solutions. For a list of certified antennas see FCC Regulatory 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 & your body.

Do not run antenna cables directly above or directly below the radio. Do not place any parts or run any high-speed digital lines below the radio. Ensure that there is the maximum allowable spacing separating the antenna connectors on the radio from the antenna. In addition, do not place antennas directly above or directly below the radio. Ezurio recommends the use of a double-shielded cable for the connection between the radio and the antenna elements. Be sure to put a 10uF/16V/0603 capacitor on EACH 3.3V power pin. Place the capacitor as close as possible to the pin to ensure correct PMU operation. Use proper electro-static-discharge (ESD) procedures when installing the Ezurio radio module. To avoid negatively impacting Tx power and receiver sensitivity, do not cover the antennas with metallic objects or components. In order to use Ezurio MT320 1420 module certification, please follow exactly the same layout and board stack as shown below. https://www.ezurio.com/

Reference Baking Conditions. Remove the Sona MT320 M.2 1420 module by using a hot air gun. This process should be carried out by a skilled technician. Recommended conditions:

One-side component platform:

Set the hot plate at 280C. Put the platform on the hot plate for 8~10 seconds. Remove the device from platform. Two-side components platform:

Use two hot air guns. On the bottom, use a pre-heated nozzle (temp setting of 200~250C) at a suitable distance from the platform PCB. On the top, apply a remove nozzle (temp setting of 330C). Heat until device can be removed from platform PCB. Platform PCB Remove Nozzle SI P Pre-heat Nozzle Remove the residue solder under the bottom side of device.

The module contains a MT7921LSN transceiver which controls the physical data rates and modulation parameters. The module contains a MT7921LSNtransceiver that has an integrated power management system, including internal voltage regulation. Antenna Connectors is RPSMA/ I-PEX MHF4L. And no external amplifier will be used with this modular. This modular is tested under stand-alone configuration. Please refer to Test setup photo. The modular transmitter is labeled with its own FCC ID number. Please refer to label sample and label location. The modular complies with this requirement. Please refer to user manual. The device complies with this requirement. Please refer to RF exposure report. Modular Approval Request FCC (KDB 996369 D01 & Part 15.212) FCC ID: SQG-MT3202230 Items to be covered by Single modular transmitters. 1. The modular transmitter must have its own RF shielding. 2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation. 3. The modular transmitter must have its own power supply regulation. 4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(b)(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). 5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. 6. The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number in accordance with 15.212 (a)(1)(vi)(A) / (B). 8. there are very strict operational and 7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 1.1310, 2.1091, 2.1093, and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance. Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance.
