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.
Frequency Range of 27 MHz to 1050 MHz Ultra-low Power ARM Cortex-M0+ 40 MHz MCU with either 64 kB FLASH High Performance Narrow-band RF-Transceiver, based on field proven AX5043 5 mm x 7 mm QFN40 package Supply Range 2.1V - 3.6 V Extremely low standby current
