1. WNFB-265AXI(BT) & AP12275_M2P User manual Introduction

This document provides customers with considerations for the hardware design of WNFB-265AXI(BT). It includes hardware block diagram, reference design, and PCB stack up, which will be explained in detail below.

1.1. Module Block Diagram

_ Figure1. WNFB-265AXI(BT) & AP12275_M2P Module Block Diagram_

In Figure 1, WNFB-265AXI(BT) & AP12275_M2P is a fully Wi-Fi and Bluetooth functionalities 2230 M.2 card (KEY E) with integrated Bluetooth 5.0. The WLAN host interface is PCIe v3.0 compliant and runs at Gen2 speeds. The Bluetooth host interface is a UART interface and it also supports PCM interface.

1.2. Reference Design

Figure2. Module Reference Design

Figure3. Interface pin define reference design

The recommended schematic configuration for all of the interfaces and GPIOs are shown as figure 4. The connection block diagram of the PCI-e interface is shown in figure 5. However, the connection block diagram of UART and PCN interfaces is shown in figure 6. The PCI-e differential pair signals impedance target is 100 ohms impedance. The length difference of each pair of differential signals does not exceed 10 mil, and the integrity of a ground plane should be maintained, as far as possible.

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 or more 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.

Any changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment

RF exposure statements

This Transmitter must not be co‐located or operating in conjunction with any other antenna or transmitter.
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body or nearby persons.
CFR 47 FCC PART 15 SUBPART C (15.247) and SUBPART E (15.407) has been investigated. It is applicable to the modular transmitter.
The devices must be installed and used in strict accordance with the manufacturer’s instructions as described in the user documentation that comes with the product.
This radio transmitter RYK-WNFB265AXIBT has been approved by Federal Communications.

Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.
Unique antenna connector (RP-SMA) must be used on the Part 15 authorized transmitters used in the host product.

Dipole| AD-303N| 3.14 dBi| 3.24 dBi|

Length of Antenna cable:150mmConnector type of Antenna cable: I-PEX/MHF4 to RP-SMA(F)

If the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: RYK-WNFB265AXIBT” Or “Contains FCC ID: RYK-WNFB265AXIBT”

The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

Industry Canada statement:

This device complies with Industry Canada license-exempt RSSs. Operation is subject to the following two conditions:

1. This device may not cause interference, and
2. This device must accept any interference, including interference that may cause undesired operation of the device.

If the ISED certification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains IC: 6158A- NFB265AXIBT”.

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.

Must use the device only in host devices that meet the FCC/ISED RF exposure category of mobile, which means the device is installed and used at distances of at least 20cm from persons.

The end user manual shall include FCC Part 15 /ISED RSS GEN compliance statements related to the transmitter as show in this manual.
Host manufacturer is responsible for compliance of the host system with module installed with all other applicable requirements for the system such as Part 15 B, ICES 003.
Host manufacturer is strongly recommended to confirm compliance with FCC/ISED requirements for the transmitter when the module is installed in the host.
Must have on the host device a label showing Contains FCC ID: 6158A- NFB265AXIBT, Contains IC: 6158A-NFB265AXIBT
The use condition limitations extend to professional users, then instructions must state that this information also extends to the host manufacturer’s instruction manual.

If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system.
