N518BS Higher-Performance Narrowband RF Transceiver Module

Overview

N518BS is a high-performance RF transceiver module engineered for ultra-reliable, long-range narrowband communication. Based on Texas Instruments CC1125 transceiver, PA, LNA, and TCXO. Up to +33 dBm (2W) output power and outstanding -126 dBm receiver sensitivity. Line-of-sight communication over 15 kilometers. Supporting critical global ISM bands (169, 433, 868, 915 MHz) via a standard SPI interface. Definitive solution for advanced metering, industrial telemetry, and any application where link reliability and range are paramount.
