Some wireless links can't afford to fail. Pipeline pressure monitors in remote deserts, grid sensors in mountain valleys, perimeter alarms at critical facilities—they need to be heard, even when the signal has to travel 16 km or punch through dense foliage and concrete.

The N519AS is built for those links.

It delivers +37 dBm (5W) output power with -126 dBm sensitivity—a link budget that enables reliable communication beyond 16 km line-of-sight. That's enough reach to connect far-flung assets without repeaters, and enough margin to punch through interference and obstacles.

Built around the Texas Instruments CC1120 narrowband transceiver and enhanced with an external high-power PA and LNA, this module is engineered for applications where data loss is not an option:

Smart grid infrastructure
Oil & gas pipeline monitoring
Industrial SCADA
Perimeter security
Long-range telemetry

The CC1120 core provides exceptional blocking and selectivity, ensuring your packets get through even in congested spectrum environments. Dedicated TXEN, RXEN, and LANEN control pins give you precise hardware sequencing, while VTCXO support enables ultra-stable frequency reference for narrowband modes and regulatory compliance.

Available in 169 MHz, 433 MHz, 868 MHz, and 915 MHz variants—including the 169 MHz band specifically tailored for European and Chinese smart grid applications—the N519AS offers global deployment flexibility in a single 36×24 mm SMD footprint.
