The N516AS-B represents the pinnacle of professional-grade, long-range wireless communication, integrating Texas Instruments' high-performance CC1120 narrowband transceiver with the CC1190 high-power RF front-end amplifier. This synergistic combination delivers an exceptional +27 dBm (500 mW) output power and outstanding -126 dBm receiver sensitivity, creating a link budget that enables reliable communication over distances exceeding 10 kilometers in line-of-sight conditions. Engineered for the most demanding industrial applications, it features a TCXO for frequency stability, comprehensive multi-level ESD protection on every pin, and a rugged 4-layer PCB design. Supporting the 868 MHz and 915 MHz ISM bands, it is fully compatible with WMBUS (Wireless M-Bus) for utility metering and Arduino for rapid prototyping, making it the definitive solution for mission-critical wireless systems.
