To facilitate the antenna tuning and certification test, a RF connector and an antenna
matching circuit should be added. The following figure is the recommended circuit.RF
trace should be 50Ω.

wireless modules
The C90 are 0Ω resistors, and the C6, C9 are reserved for tuning and have no
components. The RF test connector is used for the conducted RF performance test,
and should be placed as close as to the modules MAIN_ANT pin. The traces impedance
between WSD377 and antenna must be controlled in 50Ω.

Note:All platforms must follow this antenna matchingwhen using this module. If not follow completely, the FCC authorization is no longer considered valid.

Compliance Information
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.
FCC 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 generate, 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 the user's authority to operate the equipment.
Exposure to Radio Frequency Radiation. This equipment must be installed and operated in accordance with provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter.
End-users and installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.

For end product label, the final end product must be labeled in a visible area with the following: Contains Transmitter Module FCC ID: TK4WSD377 or Contains FCC ID: TK4WSD377
Note: (1) This device is approved for OEM installation with specified antennas as listed in this Manual. It is the responsibility of the Installer to comply with the separation distance for satisfying RF exposure compliance. (2) This device only could work when being installed into “client devices” which could not transmit automatically.
Important Note: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not 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.
Antenna Type Frequency Band (MHz) TX Paths Antenna Gain (dBi)
Dipole Antenna
OEM installation must use the antenna that its antenna gain less than above table gain.
