The radios are part of the EZRadioPRO family, which includes a complete line of transmitters, receivers, and transceivers covering a wide range of applications. All parts offer outstanding sensitivity of 129 dBm while achieving extremely low active and standby current consumption. The 69dB adjacent channel selectivity with 12.5kHz channel spacing ensures robust receive operation in harsh RF conditions, which is particularly important for narrowband operation. RX current of 10 mA coupled with extremely low standby current and fast wake times ensure extended battery life in the most demanding applications.
