N406AS Pro: 2.4 GHz LoRa® Module with Integrated High-Power PA – Product Datasheet
1. Product Overview
The N406AS Pro is a fully integrated, high-performance 2.4 GHz wireless module engineered for applications demanding maximum communication range and link robustness. It combines Semtech's leading SX1280 transceiver with an integrated, high-efficiency power amplifier (PA) and matching network, delivering a formidable output power of up to +30 dBm (1 Watt). This design, paired with the core chip's exceptional -132 dBm sensitivity, creates an unparalleled link budget exceeding 162 dB. It is the ultimate "plug-and-play" RF solution for achieving ultra-long-range, license-free communication in the globally accessible 2.4 GHz ISM band.
Why Choose the N406AS Pro?
Unmatched Range in a Module: The integrated PA eliminates the need for external RF amplification design. Achieve reliable multi-kilometer links with a simple, single-component solution.
Global Single-SKU Deployment: One hardware design operates worldwide on the 2.4 GHz band, simplifying logistics, inventory, and product certification efforts.
Superior Penetration & Reliability: The high link budget ensures excellent performance in non-line-of-sight (NLOS), urban, and industrial environments where other wireless technologies fail.
Designer-Friendly: Simplifies your PCB design by providing a complete, certified RF front-end. All complex impedance matching and PA biasing are handled on the module.
Protocol Flexible: Supports LoRa®, FLRC, and (G)FSK modulations via the SX1280 core, adaptable to various data rate and application needs.

3. Application Diagram & Integration
Simplified Design: The module appears as a single component to your host processor. The complex RF chain, including the PA, filter, and switch, is fully integrated and optimized.
Power Supply Note: The integrated PA requires a stable 5V supply capable of providing up to 1A peak current during transmission at high power. Ensure your power rail design accounts for this.
4. Applications
Ideal for systems where maximum range is critical and design simplicity is valued:
Long-Range Industrial Telemetry: Communication with remote sensors, pumps, or equipment spread over vast areas (mines, farms, wind farms).
Urban & Suburban IoT Networks: Building-to-building links, city-wide sensor networks.
Critical Infrastructure Monitoring: Power line monitoring, pipeline monitoring, water management systems.
Advanced Remote Control: For long-range drone control, robotics, and autonomous systems.
