N519BS 5W Ultra-High-Power Sub-1GHz RF Transceiver Module (CC1125) – Long Range, Critical Infrastructure

Meta Description:
The N519BS delivers +37 dBm (5W) output power with -126 dBm sensitivity, enabling reliable 16 km+ communication. Based on TI CC1125, it's ideal for smart grid, pipeline monitoring, and industrial telemetry. Available in 169/433/868/915 MHz.

📡 Product Overview

The N519BS is a high-performance Sub-1GHz RF transceiver module designed for ultra-long-range, mission-critical wireless links. With an industry-leading link budget of 163 dB (+37 dBm TX, -126 dBm RX), it achieves over 16 km line-of-sight communication at 1.2 kbps with a 3 dBi antenna.

Built around the Texas Instruments CC1125 narrowband transceiver, the module integrates an external 5W Power Amplifier (PA) and a Low-Noise Amplifier (LNA) for maximum range and robustness. The CC1125 core offers exceptional blocking and selectivity, ensuring reliable operation even in congested ISM bands.

🛠️ Design Resources

⚡ Important Design Considerations

• Power Supply: The module draws 2A peaks during transmission. Ensure your 5V supply can handle these transients with low-ESR capacitors placed close to the module.

• Antenna Selection: For maximum range, use a well-tuned antenna matched to your frequency band.

• Thermal Management: Pulsed operation keeps heat manageable. For high duty cycles, consider airflow or heatsinking.

• Regulatory Compliance: Designed to help meet FCC/ETSI standards; final certification depends on system integration and local regulations.

Specifications subject to change. Actual performance depends on antenna, environment, and system design. Ensure compliance with local radio regulations before deployment.
