Description
The RFM119W-433S1 from HopeRF is a high-performance, highly flexible RF transmitter module designed for low-cost wireless applications in the sub-1GHz spectrum. Based on a single-chip transceiver architecture, it supports (G)FSK and OOK modulation schemes, providing a robust and simple method for data transmission control via its DATA pin or configurable TWI interface.
Operating from 1.8V to 3.6V, the module is optimized for extended battery life, consuming only 27.6 mA during transmission at +10 dBm output power and dropping to a mere 20 nA in sleep mode. Its programmable features, including frequency deviation from 1.0 to 200 kHz and symbol rates up to 100 ksps, allow developers to tailor the RF link parameters for specific range, data rate, and power consumption requirements.
