Custom RF Transmission Module RTU

RFM119B RF Transmission Module RFM119B is a+20dBm high-power, high-performance RF module that supports frequencies ranging from 127 to 1020MHz, OOK, (G) FSK modulation. RFM119B has a high level of integration, simplifying the peripheral materials required in system design, making it extremely convenient for users to carry out secondary development applications. The transmission power of up to+20dBm improves the link performance of applications, and supports multiple packet formats and encoding and decoding methods, making it flexible in meeting the needs of various applications for different packet formats and encoding. In addition, RFM119B also supports 64 byte Tx FIFO, rich GPIO and interrupt configurations, Auto Tx operation mode, low voltage detection, low-frequency timed interrupt wake-up MCU, manual fast frequency hopping, and other functions, making application design more flexible and achieving product differentiation design. RFM119B operates between 1.8V and 3.6V, consuming only 23mA of emission current at+13dBm output power, and only 80mA of emission current at+20dBm output power. It is a low-power and high-efficiency choice. RFM119B RF Transmission Module
