Certification

7.1 CE Certification
MS46SF11 module is being tested and is expected to be compliant with the EU- Radio Equipment standards. OEM integrators should consult with qualified test houses to verify all regulatory requirements have been met for their complete device.
7.2 FCC Certification
MS46SF11 module is being tested and is expected to be compliant with the Federal Communications Commission standards.
7.3 Environmental
7.3.1 RoHs
MS46SF11 modules are in compliance with Directive 2011/65/EU, 2015/863/EU of the European Parliament and the Council on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
7.3.2 Reach
MS46SF11 modules listed below do not contain the 191 SVHC (Substance of Very High Concern), as defined by Directive EC/1907/2006 Article according to REACHAnnex XVII.

As for the OEM integration:
Only OEM integrators have the right to integrate this device under the following conditions: Any other transmitter or antenna must not be co-located with the antenna and transmitter. The module shall be only used with the integral antenna(s)that has been originally tested and certified with this module.
As long as the two conditions below are met, further transmitter testing will not be required. (1)This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
However, the OEM integrator shall test their end-product for any additional compliance requirements with this module installed (for example, digital device emission, PC peripheral requirements, etc. ). If these conditions cannot be met (for example certain laptop configuration or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the final product shall not use the FCC ID of the module.
In these circumstances, the OEM integrator shall be re-evaluating the end product(including the transmitter) and obtaining a separate FCC authorization. The OEM shall be verifying end product compliance with FCC Part 15, sub-part B limits for unintentional radiators through an accredited test facility.

Notes & cautions

We cannot assure that the specification has no errors and omissions even though this specification is under collate and check strictly.
This specification is under the protection of laws and regulations of copyright, please do not copy and duplicate at any form, or do not transmit part or full of this specification in any wired and wireless network in any form, or do not edit or translate to any other format, word, code, etc.

8.1 Design notes

1. It is critical to follow the recommendations of this document to ensure the module meets the specifications.
2. The module should be placed at the edge of the circuit board as far as possible to keep it away from other circuits.
3. The antenna should be kept away from other circuits. It can prevent low radiation efficiency and the normal use of other circuits from being affected.
4. The landing of components should be appropriate and that is better for reducing the parasitic inductance.
5. Please refuse to supply voltage that is not within the range of specification.
6. Please make sure the module or its surface may not suffer from physical shock or extreme stress.

8.2 Layout notes

To make sure wireless performance is in its best condition, please layout the MS46SF11 module on the carrier board as below in the instructions and pictures.

1.  Placement of the antenna area of the module shall lay clearance completely and should not be blocked by the metal. Otherwise, it will have an effect on antenna performance (As the picture indicated below).
2. Placement of top layer The placement of the top layer in the carrier board shall be laid copper completely to reduce the signal line in the carrier board or other interference.
3. Clearance The upper and below the area of the antenna (including the case) shall have 4mm or more than 4mm clearance to reduce the influences on the antenna.

*The Grey area above is the Carrier board.
8.3 Installation and soldering
(1) Please do not lay copper under the module antenna. It can prevent the influence of signal radiation and the transmission distance from being affected.
8.4 Handling and storage

1. Due to the fact that CMOS components are included in the module, it is better to eliminate static electricity at any method when transporting or working with the module. Moreover, it is strongly recommended to add anti-ESD components to circuit design to hinder damage from real-life ESD events. Anti-ESD methods can be also used in mechanical design.

2. Please store the modules within -40 to +125 before and after installation and make sure the modules is away from direct sunlight exposure for a long duration. Modules should be far away from humid and salty air conditions, and any corrosive gasses or substances.

3. Please not wash the module. No-Clean Paste is used in production. The metal shield may be oxidized by the washing process and may lead to a chemical reaction with No-Clean Paste. If modules go through the washing process, the functions of the module may not be guaranteed.

8.5 Life support applications

1. The module is not designed for life support devices or systems and is not allowed to be used in destructive devices or systems in any direct, or indirect ways. Mine is not responsible for a compensation of any losses when applying modules under such application as described above.
2. Mine shall not responsible for the customer’s products or applications.

Disclaimer

The factory has passed the ISO9001 quality management system, ISO14001 environmental management system, and OAHS18001 occupational health and safety assessment. Each product has been rigorously tested (transmission power test, sensitivity test, power consumption test, stability test, aging test, etc.).
