Product description
RFM119-433S1 is an RF transmitter module for wireless data transmission in the 433.92 MHz band, designed for low power consumption and easy integration in battery-powered systems. The module is based on an integrated transmitter IC with direct synthesis and built-in power amplifier, providing stable frequency generation. It supports FSK, GFSK, and OOK modulation. Communication and configuration via TWI, two-wire interface.
The internal frequency synthesis with low phase noise and automatic calibration at startup contributes to stable operation over temperature and supply voltage. Transmission is controlled via the DATA input or via commands, making the module suitable for microcontroller-based designs such as home automation, remote control, alarm systems, and industrial monitoring.
