Description
The CMT2119AW is an ultra-flexible, single-chip RF transmitter engineered for sub-GHz wireless applications in the 240 to 960 MHz range. As a member of the CMOSTEK “Next Gen RF” family, it is designed to provide a streamlined, high-performance solution for data transmission. It is particularly valued for its simple data-trigger mechanism: transmission starts automatically when a signal change is detected on the DATA pin, making it incredibly easy to integrate into simple remote control or signaling systems.
The device supports both TWI (Two-Wire Interface) register configuration and offline EEPROM programming via the CMOSTEK RFPDK, offering developers the choice between dynamic real-time control and fixed-function, stand-alone operation. With a sleep current of just 20 nA and highly adjustable output power, the CMT2119AW is optimized for maximum efficiency in battery-powered IoT and consumer electronics.
Note: Configuration for this device is managed via the CMOSTEK RFPDK software. Please refer to the official datasheet for detailed register descriptions, antenna matching impedance requirements, and TWI protocol specifications.
Features
- Versatile Configuration: Supports both online TWI register access and offline EEPROM programming.
- Modulation Flexibility: Supports FSK, GFSK, and OOK modulation schemes.
- Adjustable Performance: Output power is configurable from -10 to +13 dBm to balance range and battery life.
- Compact Design: Housed in a space-saving 6-pin SOT23-6 package.
- Low Power: Features an ultra-low sleep current (< 20 nA), ideal for long-term standby applications.
- Wide Frequency: Covers standard ISM bands from 240 MHz up to 960 MHz.
Benefits
- Simplicity: Native “data-pin-trigger” transmission reduces the need for complex host microcontroller software.
- Regulatory Compliance: Designed to meet FCC/ETSI standards for global deployment.
- Integration: Pairs seamlessly with the CMT2219A receiver to create a robust and cost-effective wireless link.
Applications
- Consumer Electronics: Remote fan controllers, lighting controls, and RKE (Remote Keyless Entry).
- Security: Wireless alarm systems and sensor networks.
- Industrial: Monitoring, control systems, and infrared transmitter replacements.
- Home Automation: Building automation and smart home wireless nodes.
