The ON Semiconductor AX5043 receiver is extremely robust and can achieve industry leading sensitivities as low as -137 dBm, while consuming less than 10 mA of current. For applications that require antenna diversity, an integrated diversity controller is included and can automatically control an external antenna switch through a GPIO pin. The receiver also has a wake on radio feature, which further reduces power consumption by allowing the MCU to sleep as long and as often as possible between radio events.
