The information contained herein is the exclusive property of WNC and shall not be distributed, reproduced, or disclosed in whole or in part without prior written permission of WNC. 3 / 9 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. 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 end-user regarding to Regulatory Domain change. As long as 3 conditions above are met, further transmitter test 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 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. 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: NKR-DNSA144”. 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.

Note B: QCA4004 need 3.3V and 1.2V supply. For 1.2V supply there are 2 methods: Switching and LDO. Inside the QCA4004, there is embedded a switching regulator to convert 3.3V to 1.2V for its chip core voltage supply. Also it has a LDO driver to act as 3.3V->1.2V LDO driver (might need external transistor). In

The tradeoff is we have to add a power inductor near QCA4004 chip. Also shielding height has to be caution to prevent the inductor magnetic field interaction with the iron material in the shielding.  Absolute Rating Symbol Description Range Unit VDDIO All IO supply voltage -0.3~+4.0 Volt 3.3V All 3.3V net -0.3~+4.0 Volt Min Digital IO All Digital IO pins -0.3 Volt Max Digital IO All Digital IO pins (VDDIO+0.3) Volt RFin Max Input RF signal 10 dBm Tstorage Storage Temperature -40~+135 ℃ ESD-HBM Human Body Model, all pins Volt ESD-CDM-nonRF Charged Device Model, non-RF pins 500 Volt ESD-CDM-RF Charged Device Model, RF pins 400 Volt Note: This table is the level that could permanent cause damage to the module.

There is a SPDT RFSW to do the diversity between 2 RF ports during normal mode. B. For Port0, there are 2 options, U.FL0 or printed antenna by a jumper capacitor. C. If using on board printed antenna: Please do not cover or put anything close to the printed antenna otherwise the radiation efficiency will be degraded. Also keep clean underneath the printed antenna area. D. For Port1, there are 2 options as well, U.FL1 or RF PAD by another jumper capacitor. E. RF PAD: Ideally, this can bridge the RF signal to the device outside the board. Application board designer must be caution on the impedance control of the RF pad and 50 Ohm trace at platform board.
