N541AS | +27 dBm Long Range Sub-1 GHz (G)FSK RF Module

Detail

Parameters

N541AS High-Performance, Long-Range Sub-1 GHz Wireless Module

Product Overview

N541AS is a high-performance wireless module engineered for applications demanding superior range and link reliability without the extremes of maximum power. By integrating the robust Silicon Labs Si4463 transceiver with an efficient external power amplifier (PA), it delivers a strong +27 dBm output power, enabling reliable communication over distances of several kilometers. Supporting key Sub-1 GHz ISM bands, it strikes an ideal balance between extended range, manageable power consumption, and thermal design, making it perfect for wide-area sensor networks, industrial telemetry, and advanced metering infrastructure.

Key Features & Benefits

High Power Output: Delivers +27 dBm, significantly extending range and improving signal penetration in suburban and rural environments.
Extended Operational Range: Enables reliable links over distances of 5-8 km (line-of-sight), ideal for covering large areas.
Global Multi-Band Support: Available for 169, 433, 868, and 915 MHz bands, facilitating deployment in key markets worldwide.
Excellent Receiver Sensitivity: Up to -123 dBm ensures stable and robust communication even at low data rates.
Optimized Power Profile: Maintains the Si4463's low-power advantage for extended battery life in duty-cycled applications.
Full Developer Control: All Si4463 pins are accessible via SPI, allowing complete hardware and protocol customization.
Industrial Robustness: Operates reliably across an extended temperature range (-30°C to +75°C) for challenging environments.

Applications

Industrial IoT & SCADA: Remote monitoring and control in utilities, agriculture, and manufacturing facilities.
Smart City & Infrastructure: Large-scale sensor networks for environmental monitoring, asset tracking, and smart parking.
Advanced Metering Infrastructure (AMI): Long-distance data collection for utility meters in low-density areas.
Telemetry & Remote Control: Command links for agricultural equipment, environmental sensors, and scientific monitoring.

Why Choose the N541AS?

The N541AS is the pragmatic choice for engineers who need more range than a basic module can provide, but want to avoid the complexity, cost, and higher power consumption of a full 2Watt solution. It solves the problem of covering large farms, industrial campuses, or suburban networks effectively, offering a significant range boost over +20dBm modules while remaining easier to integrate and power than its +33dBm counterpart. It's about smart performance, not just maximum power.
