RFM119B-868S2

The RFM119B is a +20dBm high-power, high-performance RF module that supports 127 to 1020 MHz frequency, OOK, (G)FSK modulation. RFM119B is highly integrated, simplifies the peripheral materials required in the system design, and is extremely convenient for users to conduct secondary development applications. Transmission power of up to +20 dBm improves the link performance of the application and supports a variety of packet cells
It can flexibly meet the needs of various applications for different packet formats and encodings.
In addition, the RFM119B also supports 64-byte Tx FIFO, rich GPIO and interrupt configuration, Auto Tx operation mode, low voltage detection, low frequency timing interrupt wake up MCU, manual fast frequency hopping and other functions, making application design more flexible, to achieve product differentiation design. Operating from 1.8V to 3.6V, the RFM119B consumes only 23 mA of transmit current at +13dBm output power and 80mA of transmit current at +20dBm output power, making it the best choice for low power consumption and high efficiency.
