3 BLOCK DIAGRAM
The following is the SDC-WB40NBT block diagram:
Note: Transmitter frequencies for Wi-Fi are 2412-2462 MHz and 5180-5805 MHz. Transmitter frequencies
for BT are 2402-2480 MHz.
The SDC-SSD40NBT block diagram displays the RF circuitry of the SDC-WB40NBT.
Note:
BT functions on the AUX port and not on the Main port. For Wi-Fi and BT single-antenna
implementations, the AUX port must be used.
IMPORTANT: When BT is transmitting high priority traffic (such as during a scan and/or when sending audio
traffic) Wi-Fi receive is sent to the main antenna port (even when set to AUX only). When high
priority transmission ends, Wi-Fi receive functionality returns to the AUX port (when set to AUX
only). For optimal Wi-Fi performance, we recommend that you populate both the Main and the
AUX ports with an antenna.
