It offers outstanding sensitivity of –126 dBm while achieving extremely low active and standby current consumption. The RFM24W offers continuous frequency coverage across the entire sub-GHz band from 142–1050 MHz with extremely fine frequency resolution. The RFM24W offers exceptional output power of up to +11 dBm with outstanding TX efficiency. The high output power and sensitivity results in an industry leading link budget of 137 dB allowing extended ranges and highly robust communication links. Its active mode TX current consumption of 19 mA at +11 dBm and RX current of 10 mA coupled with extremely low standby current and fast wake times ensure extended battery life in the most demanding applications. The module is compliant with all worldwide regulatory standards: FCC, ETSI, and ARIB. All devices are designed to be compliant with 802.15.4g and WMbus smart metering standards.
