Looking for Rfm119w Module? RF Module RFM119W-433S1 is available at Zbotic with fast shipping across India.
RF Module RFM119W-433S1
The RFM119W/RFM119SW stands as a pinnacle of performance, flexibility, and cost-effectiveness, serving as a single-chip (G)FSK/OOK transmitter catering to a wide array of wireless applications spanning the 240 to 960 MHz frequency range. As an integral member of the HOPERF Next Gen RFTM family, which encompasses a comprehensive suite of transmitters, receivers, and transceivers, the RFM119W/RFM119SW offers unrivaled simplicity in data transmission control.
Transmission initiation occurs upon detection of an effective level turnover on the DATA pin, with transmission ceasing either after the DATA pin maintains a low level for a specified time window or upon issuance of a two-wire interface (TWI) command. Configuration of the chip’s features can be achieved through two distinct methods: configuring the registers via TWI or programming the embedded RFPDK.
Operating within a voltage range of 1.8 V to 3.6 V, the device boasts exceptional efficiency, consuming a mere 27.6 mA (FSK @ 868.35 MHz) during transmission with a +10 dBm output power. Additionally, it exhibits minimal power leakage, drawing a mere 20 nA while in sleep mode. When paired with the CMT2219A receiver, the RFM119W/RFM119SW transmitter facilitates the establishment of a robust RF link, ensuring seamless communication across varied applications.

RF Module RFM119W-433S1 Overview
The RF Module RFM119W-433S1 is a single-chip (G)FSK/OOK transmitter supporting a wide 240–960 MHz frequency range, tailored for low-cost wireless links. Its fully programmable parameters make it suitable for custom remote-control, telemetry, and short-range data applications.
Key Features of RF Module RFM119W-433S1
- Frequency range: 240 to 960 MHz, configurable via onboard registers
- Supports both GFSK and OOK modulation schemes for flexible data encoding
- Compact single-chip transmitter with all features programmable
- Two-wire interface for register access and EEPROM programming
- Low operating voltage (up to 3.6 V) for battery-powered designs
- Fast shipping from Zbotic ensures you get your module quickly
Applications and Use Cases
- Wireless remote-control systems (garage doors, lighting)
- Short-range telemetry for environmental or industrial sensors
- Home automation transmitters (smart switches, alarm sensors)
- Data links for DIY robotics and RC vehicles

How to Use RF Module RFM119W-433S1
Connect VDD to a regulated 3.3–3.6 V supply and ground to GND. Use the two-wire interface (SDA/SCL) to program modulation, frequency, and output power into the onboard registers and EEPROM. Tie the DATA pin to your microcontroller’s GPIO; transmission starts on a high-to-low transition and stops when DATA remains low for the programmed window. Antenna matching and decoupling capacitors close to VDD are recommended for stable RF performance.
