RFM219B Sub-1GHz OOK / (G)FSK RF Receiver Module
127–1020MHz Sub-1GHz | -120dBm Sensitivity | 8.5mA Active RX | FCC/ETSI Compliant
The RFM219B is a highly integrated, high-performance Sub-1GHz RF receiver module operating across an ultrawide 127MHz to 1020MHz frequency range. Supporting OOK, (G)FSK, and (G)MSK demodulation schemes, it achieves exceptional link budgets with -120dBm sensitivity at just 8.5mA active RX current. Featuring versatile power-management modes down to 300nA deep sleep and 800nA low-power timing mode, it delivers superior interference immunity for battery-constrained telemetry systems.
