Bluetooth Beacon adopts BLE advertising feature to support new applications such as indoor navigation, healthcare, etc. The advertised packets are placed in the Channel 37, 38 and 39 to avoid the interference from WiFi channels at ISM band. The BC7161 is aimed for the Beacon device for various proximity aware applications.

The BC7161 is a low-cost 2.4GHz BLE Beacon transmitter. With an external 32MHz crystal (XO), an MCU and a few ceramic capacitors, it can implement a complete Beacon device. The output power level can be programmed from -10dBm to +5dBm for various applications. Maximum of +8dBm with 24mA current consumption can be achieved even for a lowcost 8-pin SOP-EP package.
