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.

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 this table we consider to use switching regulator method to have better power efficiency. 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 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. 8 / 20 material in the shielding.

A. 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.
